Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603316, here are decompositions:
- 7 + 31603309 = 31603316
- 67 + 31603249 = 31603316
- 193 + 31603123 = 31603316
- 307 + 31603009 = 31603316
- 439 + 31602877 = 31603316
- 457 + 31602859 = 31603316
- 463 + 31602853 = 31603316
- 523 + 31602793 = 31603316
Showing the first eight; more decompositions exist.
