Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477172, here are decompositions:
- 31 + 31477141 = 31477172
- 61 + 31477111 = 31477172
- 73 + 31477099 = 31477172
- 109 + 31477063 = 31477172
- 151 + 31477021 = 31477172
- 241 + 31476931 = 31477172
- 373 + 31476799 = 31477172
- 439 + 31476733 = 31477172
Showing the first eight; more decompositions exist.
