Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535456, here are decompositions:

37 + 31535419 = 31535456
79 + 31535377 = 31535456
193 + 31535263 = 31535456
223 + 31535233 = 31535456
229 + 31535227 = 31535456
283 + 31535173 = 31535456
313 + 31535143 = 31535456
349 + 31535107 = 31535456

Showing the first eight; more decompositions exist.
