Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594518, here are decompositions:
- 17 + 31594501 = 31594518
- 29 + 31594489 = 31594518
- 89 + 31594429 = 31594518
- 97 + 31594421 = 31594518
- 167 + 31594351 = 31594518
- 271 + 31594247 = 31594518
- 281 + 31594237 = 31594518
- 359 + 31594159 = 31594518
Showing the first eight; more decompositions exist.
