Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142124, here are decompositions:
- 13 + 142111 = 142124
- 67 + 142057 = 142124
- 163 + 141961 = 142124
- 193 + 141931 = 142124
- 271 + 141853 = 142124
- 313 + 141811 = 142124
- 331 + 141793 = 142124
- 457 + 141667 = 142124
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 142,124 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 142124 first appears in π at position 527,580 of the decimal expansion (the 527,580ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
