Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551762, here are decompositions:

5 + 31551757 = 31551762
29 + 31551733 = 31551762
41 + 31551721 = 31551762
79 + 31551683 = 31551762
149 + 31551613 = 31551762
163 + 31551599 = 31551762
223 + 31551539 = 31551762
311 + 31551451 = 31551762

Showing the first eight; more decompositions exist.
