Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476636, here are decompositions:

5 + 31476631 = 31476636
13 + 31476623 = 31476636
29 + 31476607 = 31476636
43 + 31476593 = 31476636
89 + 31476547 = 31476636
127 + 31476509 = 31476636
137 + 31476499 = 31476636
179 + 31476457 = 31476636

Showing the first eight; more decompositions exist.
