Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124784, here are decompositions:
- 3 + 124781 = 124784
- 7 + 124777 = 124784
- 13 + 124771 = 124784
- 31 + 124753 = 124784
- 67 + 124717 = 124784
- 151 + 124633 = 124784
- 223 + 124561 = 124784
- 241 + 124543 = 124784
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 124,784 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 124784 first appears in π at position 292,756 of the decimal expansion (the 292,756ordinal-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.
