Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551652, here are decompositions:

23 + 31551629 = 31551652
53 + 31551599 = 31551652
59 + 31551593 = 31551652
113 + 31551539 = 31551652
149 + 31551503 = 31551652
191 + 31551461 = 31551652
239 + 31551413 = 31551652
311 + 31551341 = 31551652

Showing the first eight; more decompositions exist.
