Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544006, here are decompositions:
- 19 + 31543987 = 31544006
- 79 + 31543927 = 31544006
- 103 + 31543903 = 31544006
- 163 + 31543843 = 31544006
- 223 + 31543783 = 31544006
- 229 + 31543777 = 31544006
- 283 + 31543723 = 31544006
- 337 + 31543669 = 31544006
Showing the first eight; more decompositions exist.
