Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535534, here are decompositions:

31 + 31535503 = 31535534
67 + 31535467 = 31535534
157 + 31535377 = 31535534
193 + 31535341 = 31535534
223 + 31535311 = 31535534
271 + 31535263 = 31535534
307 + 31535227 = 31535534
421 + 31535113 = 31535534

Showing the first eight; more decompositions exist.
