Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625776, here are decompositions:
- 3 + 31625773 = 31625776
- 23 + 31625753 = 31625776
- 53 + 31625723 = 31625776
- 173 + 31625603 = 31625776
- 197 + 31625579 = 31625776
- 239 + 31625537 = 31625776
- 269 + 31625507 = 31625776
- 383 + 31625393 = 31625776
Showing the first eight; more decompositions exist.
