Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531036, here are decompositions:
- 59 + 31530977 = 31531036
- 239 + 31530797 = 31531036
- 263 + 31530773 = 31531036
- 353 + 31530683 = 31531036
- 419 + 31530617 = 31531036
- 443 + 31530593 = 31531036
- 557 + 31530479 = 31531036
- 599 + 31530437 = 31531036
Showing the first eight; more decompositions exist.
