Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537036, here are decompositions:
- 53 + 31536983 = 31537036
- 173 + 31536863 = 31537036
- 263 + 31536773 = 31537036
- 317 + 31536719 = 31537036
- 653 + 31536383 = 31537036
- 677 + 31536359 = 31537036
- 683 + 31536353 = 31537036
- 743 + 31536293 = 31537036
Showing the first eight; more decompositions exist.
