Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535964, here are decompositions:
- 17 + 31535947 = 31535964
- 23 + 31535941 = 31535964
- 137 + 31535827 = 31535964
- 167 + 31535797 = 31535964
- 211 + 31535753 = 31535964
- 223 + 31535741 = 31535964
- 283 + 31535681 = 31535964
- 293 + 31535671 = 31535964
Showing the first eight; more decompositions exist.
