Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480176, here are decompositions:

47 + 31480129 = 31480176
59 + 31480117 = 31480176
73 + 31480103 = 31480176
97 + 31480079 = 31480176
127 + 31480049 = 31480176
157 + 31480019 = 31480176
227 + 31479949 = 31480176
229 + 31479947 = 31480176

Showing the first eight; more decompositions exist.
