Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603024, here are decompositions:
- 107 + 31602917 = 31603024
- 443 + 31602581 = 31603024
- 503 + 31602521 = 31603024
- 701 + 31602323 = 31603024
- 743 + 31602281 = 31603024
- 773 + 31602251 = 31603024
- 797 + 31602227 = 31603024
- 881 + 31602143 = 31603024
Showing the first eight; more decompositions exist.
