Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124428, here are decompositions:
- 61 + 124367 = 124428
- 79 + 124349 = 124428
- 89 + 124339 = 124428
- 127 + 124301 = 124428
- 131 + 124297 = 124428
- 137 + 124291 = 124428
- 151 + 124277 = 124428
- 179 + 124249 = 124428
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 124,428 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 124428 first appears in π at position 246,043 of the decimal expansion (the 246,043ordinal-suffix:rd 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.
