Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501922, here are decompositions:
- 43 + 31501879 = 31501922
- 61 + 31501861 = 31501922
- 73 + 31501849 = 31501922
- 103 + 31501819 = 31501922
- 163 + 31501759 = 31501922
- 181 + 31501741 = 31501922
- 223 + 31501699 = 31501922
- 523 + 31501399 = 31501922
Showing the first eight; more decompositions exist.
