Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535622, here are decompositions:

29 + 31535593 = 31535622
31 + 31535591 = 31535622
71 + 31535551 = 31535622
73 + 31535549 = 31535622
193 + 31535429 = 31535622
199 + 31535423 = 31535622
211 + 31535411 = 31535622
241 + 31535381 = 31535622

Showing the first eight; more decompositions exist.
