Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530304, here are decompositions:
- 11 + 31530293 = 31530304
- 101 + 31530203 = 31530304
- 107 + 31530197 = 31530304
- 131 + 31530173 = 31530304
- 461 + 31529843 = 31530304
- 521 + 31529783 = 31530304
- 587 + 31529717 = 31530304
- 653 + 31529651 = 31530304
Showing the first eight; more decompositions exist.
