Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460782, here are decompositions:
- 53 + 31460729 = 31460782
- 173 + 31460609 = 31460782
- 233 + 31460549 = 31460782
- 383 + 31460399 = 31460782
- 443 + 31460339 = 31460782
- 461 + 31460321 = 31460782
- 491 + 31460291 = 31460782
- 503 + 31460279 = 31460782
Showing the first eight; more decompositions exist.
