Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603692, here are decompositions:
- 11 + 31603681 = 31603692
- 79 + 31603613 = 31603692
- 83 + 31603609 = 31603692
- 139 + 31603553 = 31603692
- 173 + 31603519 = 31603692
- 181 + 31603511 = 31603692
- 311 + 31603381 = 31603692
- 331 + 31603361 = 31603692
Showing the first eight; more decompositions exist.
