Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535284, here are decompositions:

71 + 31535213 = 31535284
101 + 31535183 = 31535284
113 + 31535171 = 31535284
227 + 31535057 = 31535284
251 + 31535033 = 31535284
593 + 31534691 = 31535284
647 + 31534637 = 31535284
653 + 31534631 = 31535284

Showing the first eight; more decompositions exist.
