Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78072, here are decompositions:
- 13 + 78059 = 78072
- 23 + 78049 = 78072
- 31 + 78041 = 78072
- 41 + 78031 = 78072
- 73 + 77999 = 78072
- 89 + 77983 = 78072
- 103 + 77969 = 78072
- 139 + 77933 = 78072
Showing the first eight; more decompositions exist.
