Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122124, here are decompositions:
- 7 + 122117 = 122124
- 43 + 122081 = 122124
- 71 + 122053 = 122124
- 73 + 122051 = 122124
- 83 + 122041 = 122124
- 97 + 122027 = 122124
- 103 + 122021 = 122124
- 113 + 122011 = 122124
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 122,124 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 122124 first appears in π at position 893,899 of the decimal expansion (the 893,899ordinal-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.
