Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78390, here are decompositions:
- 23 + 78367 = 78390
- 43 + 78347 = 78390
- 73 + 78317 = 78390
- 79 + 78311 = 78390
- 83 + 78307 = 78390
- 89 + 78301 = 78390
- 107 + 78283 = 78390
- 113 + 78277 = 78390
Showing the first eight; more decompositions exist.
