Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78530, here are decompositions:
- 13 + 78517 = 78530
- 19 + 78511 = 78530
- 43 + 78487 = 78530
- 103 + 78427 = 78530
- 163 + 78367 = 78530
- 223 + 78307 = 78530
- 229 + 78301 = 78530
- 271 + 78259 = 78530
Showing the first eight; more decompositions exist.
