Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124390, here are decompositions:
- 23 + 124367 = 124390
- 41 + 124349 = 124390
- 47 + 124343 = 124390
- 53 + 124337 = 124390
- 89 + 124301 = 124390
- 113 + 124277 = 124390
- 191 + 124199 = 124390
- 197 + 124193 = 124390
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 124,390 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 124390 first appears in π at position 919,182 of the decimal expansion (the 919,182ordinal-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.
