Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535646, here are decompositions:

7 + 31535639 = 31535646
13 + 31535633 = 31535646
53 + 31535593 = 31535646
97 + 31535549 = 31535646
179 + 31535467 = 31535646
223 + 31535423 = 31535646
227 + 31535419 = 31535646
229 + 31535417 = 31535646

Showing the first eight; more decompositions exist.
