Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530790, here are decompositions:
- 17 + 31530773 = 31530790
- 89 + 31530701 = 31530790
- 107 + 31530683 = 31530790
- 131 + 31530659 = 31530790
- 149 + 31530641 = 31530790
- 173 + 31530617 = 31530790
- 197 + 31530593 = 31530790
- 293 + 31530497 = 31530790
Showing the first eight; more decompositions exist.
