Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535666, here are decompositions:

73 + 31535593 = 31535666
163 + 31535503 = 31535666
199 + 31535467 = 31535666
433 + 31535233 = 31535666
439 + 31535227 = 31535666
523 + 31535143 = 31535666
607 + 31535059 = 31535666
787 + 31534879 = 31535666

Showing the first eight; more decompositions exist.
