Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544720, here are decompositions:
- 3 + 31544717 = 31544720
- 7 + 31544713 = 31544720
- 211 + 31544509 = 31544720
- 349 + 31544371 = 31544720
- 373 + 31544347 = 31544720
- 397 + 31544323 = 31544720
- 409 + 31544311 = 31544720
- 439 + 31544281 = 31544720
Showing the first eight; more decompositions exist.
