Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463188, here are decompositions:

41 + 31463147 = 31463188
89 + 31463099 = 31463188
101 + 31463087 = 31463188
257 + 31462931 = 31463188
311 + 31462877 = 31463188
431 + 31462757 = 31463188
599 + 31462589 = 31463188
641 + 31462547 = 31463188

Showing the first eight; more decompositions exist.
