Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79688, here are decompositions:
- 19 + 79669 = 79688
- 31 + 79657 = 79688
- 61 + 79627 = 79688
- 67 + 79621 = 79688
- 79 + 79609 = 79688
- 109 + 79579 = 79688
- 127 + 79561 = 79688
- 139 + 79549 = 79688
Showing the first eight; more decompositions exist.
