Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544900, here are decompositions:
- 43 + 31544857 = 31544900
- 73 + 31544827 = 31544900
- 151 + 31544749 = 31544900
- 181 + 31544719 = 31544900
- 313 + 31544587 = 31544900
- 349 + 31544551 = 31544900
- 367 + 31544533 = 31544900
- 577 + 31544323 = 31544900
Showing the first eight; more decompositions exist.
