Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476348, here are decompositions:

5 + 31476343 = 31476348
31 + 31476317 = 31476348
97 + 31476251 = 31476348
109 + 31476239 = 31476348
179 + 31476169 = 31476348
191 + 31476157 = 31476348
199 + 31476149 = 31476348
229 + 31476119 = 31476348

Showing the first eight; more decompositions exist.
