Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31790, here are decompositions:
- 19 + 31771 = 31790
- 61 + 31729 = 31790
- 67 + 31723 = 31790
- 103 + 31687 = 31790
- 127 + 31663 = 31790
- 163 + 31627 = 31790
- 223 + 31567 = 31790
- 277 + 31513 = 31790
Showing the first eight; more decompositions exist.
