Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544000, here are decompositions:
- 3 + 31543997 = 31544000
- 13 + 31543987 = 31544000
- 73 + 31543927 = 31544000
- 97 + 31543903 = 31544000
- 127 + 31543873 = 31544000
- 157 + 31543843 = 31544000
- 223 + 31543777 = 31544000
- 277 + 31543723 = 31544000
Showing the first eight; more decompositions exist.
