Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530616, here are decompositions:
- 23 + 31530593 = 31530616
- 137 + 31530479 = 31530616
- 179 + 31530437 = 31530616
- 197 + 31530419 = 31530616
- 233 + 31530383 = 31530616
- 239 + 31530377 = 31530616
- 269 + 31530347 = 31530616
- 347 + 31530269 = 31530616
Showing the first eight; more decompositions exist.
