Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455836, here are decompositions:
- 7 + 31455829 = 31455836
- 109 + 31455727 = 31455836
- 199 + 31455637 = 31455836
- 337 + 31455499 = 31455836
- 409 + 31455427 = 31455836
- 439 + 31455397 = 31455836
- 523 + 31455313 = 31455836
- 613 + 31455223 = 31455836
Showing the first eight; more decompositions exist.
