Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482656, here are decompositions:

13 + 31482643 = 31482656
43 + 31482613 = 31482656
97 + 31482559 = 31482656
157 + 31482499 = 31482656
229 + 31482427 = 31482656
307 + 31482349 = 31482656
313 + 31482343 = 31482656
349 + 31482307 = 31482656

Showing the first eight; more decompositions exist.
