Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530598, here are decompositions:
- 5 + 31530593 = 31530598
- 101 + 31530497 = 31530598
- 179 + 31530419 = 31530598
- 251 + 31530347 = 31530598
- 257 + 31530341 = 31530598
- 401 + 31530197 = 31530598
- 569 + 31530029 = 31530598
- 881 + 31529717 = 31530598
Showing the first eight; more decompositions exist.
