Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978040, here are decompositions:
- 3 + 978037 = 978040
- 23 + 978017 = 978040
- 29 + 978011 = 978040
- 113 + 977927 = 978040
- 179 + 977861 = 978040
- 191 + 977849 = 978040
- 227 + 977813 = 978040
- 293 + 977747 = 978040
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 978,040 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 978040 first appears in π at position 300,658 of the decimal expansion (the 300,658ordinal-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.
