Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124122, here are decompositions:
- 101 + 124021 = 124122
- 139 + 123983 = 124122
- 149 + 123973 = 124122
- 181 + 123941 = 124122
- 191 + 123931 = 124122
- 199 + 123923 = 124122
- 211 + 123911 = 124122
- 269 + 123853 = 124122
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 124,122 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 124122 first appears in π at position 974,282 of the decimal expansion (the 974,282ordinal-suffix:nd 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.
