Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482156, here are decompositions:

37 + 31482119 = 31482156
53 + 31482103 = 31482156
59 + 31482097 = 31482156
67 + 31482089 = 31482156
73 + 31482083 = 31482156
89 + 31482067 = 31482156
109 + 31482047 = 31482156
113 + 31482043 = 31482156

Showing the first eight; more decompositions exist.
