Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565952, here are decompositions:
- 23 + 31565929 = 31565952
- 83 + 31565869 = 31565952
- 101 + 31565851 = 31565952
- 149 + 31565803 = 31565952
- 181 + 31565771 = 31565952
- 191 + 31565761 = 31565952
- 239 + 31565713 = 31565952
- 251 + 31565701 = 31565952
Showing the first eight; more decompositions exist.
