Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611952, here are decompositions:
- 11 + 31611941 = 31611952
- 41 + 31611911 = 31611952
- 59 + 31611893 = 31611952
- 83 + 31611869 = 31611952
- 101 + 31611851 = 31611952
- 149 + 31611803 = 31611952
- 191 + 31611761 = 31611952
- 233 + 31611719 = 31611952
Showing the first eight; more decompositions exist.
