Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972478, here are decompositions:
- 5 + 972473 = 972478
- 47 + 972431 = 972478
- 71 + 972407 = 972478
- 131 + 972347 = 972478
- 149 + 972329 = 972478
- 251 + 972227 = 972478
- 257 + 972221 = 972478
- 281 + 972197 = 972478
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 972,478 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 972478 first appears in π at position 300,445 of the decimal expansion (the 300,445ordinal-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.
