Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535634, here are decompositions:

41 + 31535593 = 31535634
43 + 31535591 = 31535634
83 + 31535551 = 31535634
131 + 31535503 = 31535634
167 + 31535467 = 31535634
211 + 31535423 = 31535634
223 + 31535411 = 31535634
257 + 31535377 = 31535634

Showing the first eight; more decompositions exist.
