Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495196, here are decompositions:

43 + 31495153 = 31495196
79 + 31495117 = 31495196
193 + 31495003 = 31495196
277 + 31494919 = 31495196
379 + 31494817 = 31495196
433 + 31494763 = 31495196
613 + 31494583 = 31495196
643 + 31494553 = 31495196

Showing the first eight; more decompositions exist.
