Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536548, here are decompositions:
- 19 + 31536529 = 31536548
- 67 + 31536481 = 31536548
- 151 + 31536397 = 31536548
- 157 + 31536391 = 31536548
- 487 + 31536061 = 31536548
- 499 + 31536049 = 31536548
- 601 + 31535947 = 31536548
- 607 + 31535941 = 31536548
Showing the first eight; more decompositions exist.
