Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124788, here are decompositions:
- 5 + 124783 = 124788
- 7 + 124781 = 124788
- 11 + 124777 = 124788
- 17 + 124771 = 124788
- 19 + 124769 = 124788
- 29 + 124759 = 124788
- 67 + 124721 = 124788
- 71 + 124717 = 124788
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 124,788 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 124788 first appears in π at position 424,040 of the decimal expansion (the 424,040ordinal-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.
