Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476282, here are decompositions:

31 + 31476251 = 31476282
43 + 31476239 = 31476282
113 + 31476169 = 31476282
139 + 31476143 = 31476282
163 + 31476119 = 31476282
223 + 31476059 = 31476282
251 + 31476031 = 31476282
269 + 31476013 = 31476282

Showing the first eight; more decompositions exist.
