Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79640, here are decompositions:
- 7 + 79633 = 79640
- 13 + 79627 = 79640
- 19 + 79621 = 79640
- 31 + 79609 = 79640
- 61 + 79579 = 79640
- 79 + 79561 = 79640
- 103 + 79537 = 79640
- 109 + 79531 = 79640
Showing the first eight; more decompositions exist.
