Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476258, here are decompositions:

7 + 31476251 = 31476258
19 + 31476239 = 31476258
71 + 31476187 = 31476258
89 + 31476169 = 31476258
101 + 31476157 = 31476258
109 + 31476149 = 31476258
139 + 31476119 = 31476258
199 + 31476059 = 31476258

Showing the first eight; more decompositions exist.
