Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77570, here are decompositions:
- 7 + 77563 = 77570
- 13 + 77557 = 77570
- 19 + 77551 = 77570
- 43 + 77527 = 77570
- 61 + 77509 = 77570
- 79 + 77491 = 77570
- 139 + 77431 = 77570
- 151 + 77419 = 77570
Showing the first eight; more decompositions exist.
