Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556558, here are decompositions:
- 79 + 31556479 = 31556558
- 97 + 31556461 = 31556558
- 151 + 31556407 = 31556558
- 409 + 31556149 = 31556558
- 547 + 31556011 = 31556558
- 577 + 31555981 = 31556558
- 601 + 31555957 = 31556558
- 619 + 31555939 = 31556558
Showing the first eight; more decompositions exist.
