Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510476, here are decompositions:

17 + 31510459 = 31510476
29 + 31510447 = 31510476
43 + 31510433 = 31510476
73 + 31510403 = 31510476
79 + 31510397 = 31510476
89 + 31510387 = 31510476
113 + 31510363 = 31510476
157 + 31510319 = 31510476

Showing the first eight; more decompositions exist.
