Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592886, here are decompositions:

37 + 31592849 = 31592886
43 + 31592843 = 31592886
53 + 31592833 = 31592886
89 + 31592797 = 31592886
107 + 31592779 = 31592886
113 + 31592773 = 31592886
139 + 31592747 = 31592886
223 + 31592663 = 31592886

Showing the first eight; more decompositions exist.
