Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626444, here are decompositions:
- 7 + 31626437 = 31626444
- 23 + 31626421 = 31626444
- 37 + 31626407 = 31626444
- 61 + 31626383 = 31626444
- 67 + 31626377 = 31626444
- 107 + 31626337 = 31626444
- 197 + 31626247 = 31626444
- 211 + 31626233 = 31626444
Showing the first eight; more decompositions exist.
