Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78480, here are decompositions:
- 13 + 78467 = 78480
- 41 + 78439 = 78480
- 43 + 78437 = 78480
- 53 + 78427 = 78480
- 79 + 78401 = 78480
- 113 + 78367 = 78480
- 139 + 78341 = 78480
- 163 + 78317 = 78480
Showing the first eight; more decompositions exist.
