Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536074, here are decompositions:

13 + 31536061 = 31536074
127 + 31535947 = 31536074
277 + 31535797 = 31536074
523 + 31535551 = 31536074
571 + 31535503 = 31536074
607 + 31535467 = 31536074
733 + 31535341 = 31536074
811 + 31535263 = 31536074

Showing the first eight; more decompositions exist.
