Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536752, here are decompositions:
- 19 + 31536733 = 31536752
- 139 + 31536613 = 31536752
- 223 + 31536529 = 31536752
- 271 + 31536481 = 31536752
- 349 + 31536403 = 31536752
- 439 + 31536313 = 31536752
- 691 + 31536061 = 31536752
- 733 + 31536019 = 31536752
Showing the first eight; more decompositions exist.
