Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552656, here are decompositions:

13 + 31552643 = 31552656
17 + 31552639 = 31552656
53 + 31552603 = 31552656
67 + 31552589 = 31552656
103 + 31552553 = 31552656
167 + 31552489 = 31552656
227 + 31552429 = 31552656
263 + 31552393 = 31552656

Showing the first eight; more decompositions exist.
