Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78330, here are decompositions:
- 13 + 78317 = 78330
- 19 + 78311 = 78330
- 23 + 78307 = 78330
- 29 + 78301 = 78330
- 47 + 78283 = 78330
- 53 + 78277 = 78330
- 71 + 78259 = 78330
- 89 + 78241 = 78330
Showing the first eight; more decompositions exist.
