Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495114, here are decompositions:

5 + 31495109 = 31495114
71 + 31495043 = 31495114
191 + 31494923 = 31495114
227 + 31494887 = 31495114
347 + 31494767 = 31495114
401 + 31494713 = 31495114
503 + 31494611 = 31495114
617 + 31494497 = 31495114

Showing the first eight; more decompositions exist.
