Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564606, here are decompositions:

89 + 31564517 = 31564606
167 + 31564439 = 31564606
173 + 31564433 = 31564606
443 + 31564163 = 31564606
449 + 31564157 = 31564606
467 + 31564139 = 31564606
503 + 31564103 = 31564606
617 + 31563989 = 31564606

Showing the first eight; more decompositions exist.
