Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457338, here are decompositions:

41 + 31457297 = 31457338
71 + 31457267 = 31457338
137 + 31457201 = 31457338
167 + 31457171 = 31457338
179 + 31457159 = 31457338
239 + 31457099 = 31457338
257 + 31457081 = 31457338
389 + 31456949 = 31457338

Showing the first eight; more decompositions exist.
