Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536144, here are decompositions:
- 43 + 31536101 = 31536144
- 47 + 31536097 = 31536144
- 83 + 31536061 = 31536144
- 127 + 31536017 = 31536144
- 163 + 31535981 = 31536144
- 197 + 31535947 = 31536144
- 313 + 31535831 = 31536144
- 317 + 31535827 = 31536144
Showing the first eight; more decompositions exist.
