Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478724, here are decompositions:
- 13 + 478711 = 478724
- 73 + 478651 = 478724
- 97 + 478627 = 478724
- 151 + 478573 = 478724
- 193 + 478531 = 478724
- 241 + 478483 = 478724
- 271 + 478453 = 478724
- 283 + 478441 = 478724
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 478,724 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 478724 first appears in π at position 470,656 of the decimal expansion (the 470,656ordinal-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.
