Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8696688, here are decompositions:
- 17 + 8696671 = 8696688
- 37 + 8696651 = 8696688
- 59 + 8696629 = 8696688
- 61 + 8696627 = 8696688
- 71 + 8696617 = 8696688
- 79 + 8696609 = 8696688
- 107 + 8696581 = 8696688
- 127 + 8696561 = 8696688
Showing the first eight; more decompositions exist.
