Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625562, here are decompositions:

53 + 31625509 = 31625562
109 + 31625453 = 31625562
131 + 31625431 = 31625562
151 + 31625411 = 31625562
179 + 31625383 = 31625562
181 + 31625381 = 31625562
211 + 31625351 = 31625562
281 + 31625281 = 31625562

Showing the first eight; more decompositions exist.
