Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534782, here are decompositions:

29 + 31534753 = 31534782
31 + 31534751 = 31534782
43 + 31534739 = 31534782
53 + 31534729 = 31534782
73 + 31534709 = 31534782
113 + 31534669 = 31534782
131 + 31534651 = 31534782
151 + 31534631 = 31534782

Showing the first eight; more decompositions exist.
