Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31774, here are decompositions:
- 3 + 31771 = 31774
- 5 + 31769 = 31774
- 23 + 31751 = 31774
- 47 + 31727 = 31774
- 53 + 31721 = 31774
- 107 + 31667 = 31774
- 131 + 31643 = 31774
- 167 + 31607 = 31774
Showing the first eight; more decompositions exist.
