Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626834, here are decompositions:
- 7 + 31626827 = 31626834
- 37 + 31626797 = 31626834
- 47 + 31626787 = 31626834
- 67 + 31626767 = 31626834
- 167 + 31626667 = 31626834
- 227 + 31626607 = 31626834
- 263 + 31626571 = 31626834
- 271 + 31626563 = 31626834
Showing the first eight; more decompositions exist.
