Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31814, here are decompositions:
- 43 + 31771 = 31814
- 73 + 31741 = 31814
- 127 + 31687 = 31814
- 151 + 31663 = 31814
- 157 + 31657 = 31814
- 241 + 31573 = 31814
- 271 + 31543 = 31814
- 283 + 31531 = 31814
Showing the first eight; more decompositions exist.
