Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534842, here are decompositions:

11 + 31534831 = 31534842
23 + 31534819 = 31534842
41 + 31534801 = 31534842
43 + 31534799 = 31534842
89 + 31534753 = 31534842
103 + 31534739 = 31534842
113 + 31534729 = 31534842
151 + 31534691 = 31534842

Showing the first eight; more decompositions exist.
