Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536068, here are decompositions:

7 + 31536061 = 31536068
19 + 31536049 = 31536068
127 + 31535941 = 31536068
241 + 31535827 = 31536068
271 + 31535797 = 31536068
397 + 31535671 = 31536068
601 + 31535467 = 31536068
691 + 31535377 = 31536068

Showing the first eight; more decompositions exist.
