Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544500, here are decompositions:
- 83 + 31544417 = 31544500
- 107 + 31544393 = 31544500
- 137 + 31544363 = 31544500
- 293 + 31544207 = 31544500
- 311 + 31544189 = 31544500
- 347 + 31544153 = 31544500
- 401 + 31544099 = 31544500
- 443 + 31544057 = 31544500
Showing the first eight; more decompositions exist.
