Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510348, here are decompositions:

29 + 31510319 = 31510348
131 + 31510217 = 31510348
179 + 31510169 = 31510348
227 + 31510121 = 31510348
257 + 31510091 = 31510348
269 + 31510079 = 31510348
347 + 31510001 = 31510348
557 + 31509791 = 31510348

Showing the first eight; more decompositions exist.
