Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534758, here are decompositions:

5 + 31534753 = 31534758
7 + 31534751 = 31534758
19 + 31534739 = 31534758
29 + 31534729 = 31534758
67 + 31534691 = 31534758
89 + 31534669 = 31534758
107 + 31534651 = 31534758
127 + 31534631 = 31534758

Showing the first eight; more decompositions exist.
