Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544350, here are decompositions:
- 3 + 31544347 = 31544350
- 53 + 31544297 = 31544350
- 137 + 31544213 = 31544350
- 179 + 31544171 = 31544350
- 197 + 31544153 = 31544350
- 251 + 31544099 = 31544350
- 293 + 31544057 = 31544350
- 311 + 31544039 = 31544350
Showing the first eight; more decompositions exist.
