Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534798, here are decompositions:

11 + 31534787 = 31534798
41 + 31534757 = 31534798
47 + 31534751 = 31534798
59 + 31534739 = 31534798
89 + 31534709 = 31534798
107 + 31534691 = 31534798
167 + 31534631 = 31534798
311 + 31534487 = 31534798

Showing the first eight; more decompositions exist.
