Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78408, here are decompositions:
- 7 + 78401 = 78408
- 41 + 78367 = 78408
- 61 + 78347 = 78408
- 67 + 78341 = 78408
- 97 + 78311 = 78408
- 101 + 78307 = 78408
- 107 + 78301 = 78408
- 131 + 78277 = 78408
Showing the first eight; more decompositions exist.
