Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544490, here are decompositions:
- 73 + 31544417 = 31544490
- 97 + 31544393 = 31544490
- 127 + 31544363 = 31544490
- 167 + 31544323 = 31544490
- 179 + 31544311 = 31544490
- 193 + 31544297 = 31544490
- 269 + 31544221 = 31544490
- 277 + 31544213 = 31544490
Showing the first eight; more decompositions exist.
