Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536154, here are decompositions:

53 + 31536101 = 31536154
101 + 31536053 = 31536154
137 + 31536017 = 31536154
173 + 31535981 = 31536154
401 + 31535753 = 31536154
521 + 31535633 = 31536154
563 + 31535591 = 31536154
743 + 31535411 = 31536154

Showing the first eight; more decompositions exist.
