Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544888, here are decompositions:
- 31 + 31544857 = 31544888
- 61 + 31544827 = 31544888
- 139 + 31544749 = 31544888
- 337 + 31544551 = 31544888
- 379 + 31544509 = 31544888
- 541 + 31544347 = 31544888
- 577 + 31544311 = 31544888
- 607 + 31544281 = 31544888
Showing the first eight; more decompositions exist.
