Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535328, here are decompositions:
- 7 + 31535321 = 31535328
- 17 + 31535311 = 31535328
- 101 + 31535227 = 31535328
- 109 + 31535219 = 31535328
- 157 + 31535171 = 31535328
- 197 + 31535131 = 31535328
- 269 + 31535059 = 31535328
- 271 + 31535057 = 31535328
Showing the first eight; more decompositions exist.
