Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497982, here are decompositions:
- 3 + 31497979 = 31497982
- 41 + 31497941 = 31497982
- 53 + 31497929 = 31497982
- 179 + 31497803 = 31497982
- 281 + 31497701 = 31497982
- 311 + 31497671 = 31497982
- 431 + 31497551 = 31497982
- 491 + 31497491 = 31497982
Showing the first eight; more decompositions exist.
