Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450762, here are decompositions:

23 + 31450739 = 31450762
41 + 31450721 = 31450762
149 + 31450613 = 31450762
173 + 31450589 = 31450762
179 + 31450583 = 31450762
311 + 31450451 = 31450762
353 + 31450409 = 31450762
449 + 31450313 = 31450762

Showing the first eight; more decompositions exist.
