Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142130, here are decompositions:
- 7 + 142123 = 142130
- 19 + 142111 = 142130
- 31 + 142099 = 142130
- 73 + 142057 = 142130
- 139 + 141991 = 142130
- 193 + 141937 = 142130
- 199 + 141931 = 142130
- 223 + 141907 = 142130
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 142,130 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 142130 first appears in π at position 789,335 of the decimal expansion (the 789,335ordinal-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.
