Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463142, here are decompositions:

5 + 31463137 = 31463142
19 + 31463123 = 31463142
43 + 31463099 = 31463142
59 + 31463083 = 31463142
79 + 31463063 = 31463142
163 + 31462979 = 31463142
173 + 31462969 = 31463142
211 + 31462931 = 31463142

Showing the first eight; more decompositions exist.
