Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708688, here are decompositions:
- 31 + 8708657 = 8708688
- 61 + 8708627 = 8708688
- 67 + 8708621 = 8708688
- 71 + 8708617 = 8708688
- 97 + 8708591 = 8708688
- 151 + 8708537 = 8708688
- 167 + 8708521 = 8708688
- 179 + 8708509 = 8708688
Showing the first eight; more decompositions exist.
