Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611936, here are decompositions:
- 19 + 31611917 = 31611936
- 29 + 31611907 = 31611936
- 43 + 31611893 = 31611936
- 53 + 31611883 = 31611936
- 67 + 31611869 = 31611936
- 107 + 31611829 = 31611936
- 179 + 31611757 = 31611936
- 199 + 31611737 = 31611936
Showing the first eight; more decompositions exist.
