Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535736, here are decompositions:

19 + 31535717 = 31535736
79 + 31535657 = 31535736
97 + 31535639 = 31535736
103 + 31535633 = 31535736
233 + 31535503 = 31535736
269 + 31535467 = 31535736
307 + 31535429 = 31535736
313 + 31535423 = 31535736

Showing the first eight; more decompositions exist.
