Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603916, here are decompositions:
- 37 + 31603879 = 31603916
- 73 + 31603843 = 31603916
- 199 + 31603717 = 31603916
- 307 + 31603609 = 31603916
- 349 + 31603567 = 31603916
- 397 + 31603519 = 31603916
- 523 + 31603393 = 31603916
- 607 + 31603309 = 31603916
Showing the first eight; more decompositions exist.
