Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495108, here are decompositions:

89 + 31495019 = 31495108
401 + 31494707 = 31495108
419 + 31494689 = 31495108
599 + 31494509 = 31495108
641 + 31494467 = 31495108
677 + 31494431 = 31495108
719 + 31494389 = 31495108
761 + 31494347 = 31495108

Showing the first eight; more decompositions exist.
