Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124124, here are decompositions:
- 3 + 124121 = 124124
- 37 + 124087 = 124124
- 103 + 124021 = 124124
- 127 + 123997 = 124124
- 151 + 123973 = 124124
- 193 + 123931 = 124124
- 271 + 123853 = 124124
- 307 + 123817 = 124124
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 124,124 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 124124 first appears in π at position 120,759 of the decimal expansion (the 120,759ordinal-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.
