Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535116, here are decompositions:

3 + 31535113 = 31535116
59 + 31535057 = 31535116
83 + 31535033 = 31535116
317 + 31534799 = 31535116
359 + 31534757 = 31535116
479 + 31534637 = 31535116
563 + 31534553 = 31535116
659 + 31534457 = 31535116

Showing the first eight; more decompositions exist.
