Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530366, here are decompositions:
- 17 + 31530349 = 31530366
- 19 + 31530347 = 31530366
- 73 + 31530293 = 31530366
- 97 + 31530269 = 31530366
- 163 + 31530203 = 31530366
- 193 + 31530173 = 31530366
- 223 + 31530143 = 31530366
- 269 + 31530097 = 31530366
Showing the first eight; more decompositions exist.
