Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536588, here are decompositions:
- 37 + 31536551 = 31536588
- 59 + 31536529 = 31536588
- 67 + 31536521 = 31536588
- 89 + 31536499 = 31536588
- 107 + 31536481 = 31536588
- 191 + 31536397 = 31536588
- 197 + 31536391 = 31536588
- 227 + 31536361 = 31536588
Showing the first eight; more decompositions exist.
