Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80690, here are decompositions:
- 3 + 80687 = 80690
- 7 + 80683 = 80690
- 13 + 80677 = 80690
- 19 + 80671 = 80690
- 61 + 80629 = 80690
- 79 + 80611 = 80690
- 163 + 80527 = 80690
- 199 + 80491 = 80690
Showing the first eight; more decompositions exist.
