Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638126, here are decompositions:
- 5 + 8638121 = 8638126
- 59 + 8638067 = 8638126
- 83 + 8638043 = 8638126
- 173 + 8637953 = 8638126
- 197 + 8637929 = 8638126
- 257 + 8637869 = 8638126
- 347 + 8637779 = 8638126
- 509 + 8637617 = 8638126
Showing the first eight; more decompositions exist.
