Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535508, here are decompositions:

5 + 31535503 = 31535508
41 + 31535467 = 31535508
79 + 31535429 = 31535508
89 + 31535419 = 31535508
97 + 31535411 = 31535508
127 + 31535381 = 31535508
131 + 31535377 = 31535508
167 + 31535341 = 31535508

Showing the first eight; more decompositions exist.
