Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476252, here are decompositions:

13 + 31476239 = 31476252
83 + 31476169 = 31476252
103 + 31476149 = 31476252
109 + 31476143 = 31476252
139 + 31476113 = 31476252
179 + 31476073 = 31476252
193 + 31476059 = 31476252
239 + 31476013 = 31476252

Showing the first eight; more decompositions exist.
