Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495234, here are decompositions:

47 + 31495187 = 31495234
191 + 31495043 = 31495234
311 + 31494923 = 31495234
347 + 31494887 = 31495234
467 + 31494767 = 31495234
521 + 31494713 = 31495234
653 + 31494581 = 31495234
887 + 31494347 = 31495234

Showing the first eight; more decompositions exist.
