Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544400, here are decompositions:
- 7 + 31544393 = 31544400
- 29 + 31544371 = 31544400
- 37 + 31544363 = 31544400
- 53 + 31544347 = 31544400
- 89 + 31544311 = 31544400
- 103 + 31544297 = 31544400
- 179 + 31544221 = 31544400
- 193 + 31544207 = 31544400
Showing the first eight; more decompositions exist.
