Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556764, here are decompositions:
- 17 + 31556747 = 31556764
- 23 + 31556741 = 31556764
- 227 + 31556537 = 31556764
- 263 + 31556501 = 31556764
- 347 + 31556417 = 31556764
- 383 + 31556381 = 31556764
- 461 + 31556303 = 31556764
- 521 + 31556243 = 31556764
Showing the first eight; more decompositions exist.
