Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31698, here are decompositions:
- 11 + 31687 = 31698
- 31 + 31667 = 31698
- 41 + 31657 = 31698
- 71 + 31627 = 31698
- 97 + 31601 = 31698
- 131 + 31567 = 31698
- 151 + 31547 = 31698
- 157 + 31541 = 31698
Showing the first eight; more decompositions exist.
