Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495126, here are decompositions:

17 + 31495109 = 31495126
83 + 31495043 = 31495126
107 + 31495019 = 31495126
239 + 31494887 = 31495126
317 + 31494809 = 31495126
359 + 31494767 = 31495126
389 + 31494737 = 31495126
419 + 31494707 = 31495126

Showing the first eight; more decompositions exist.
