Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477252, here are decompositions:

71 + 31477181 = 31477252
89 + 31477163 = 31477252
173 + 31477079 = 31477252
293 + 31476959 = 31477252
431 + 31476821 = 31477252
509 + 31476743 = 31477252
641 + 31476611 = 31477252
659 + 31476593 = 31477252

Showing the first eight; more decompositions exist.
