Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480132, here are decompositions:

3 + 31480129 = 31480132
29 + 31480103 = 31480132
41 + 31480091 = 31480132
53 + 31480079 = 31480132
71 + 31480061 = 31480132
83 + 31480049 = 31480132
113 + 31480019 = 31480132
251 + 31479881 = 31480132

Showing the first eight; more decompositions exist.
