Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495348, here are decompositions:

107 + 31495241 = 31495348
149 + 31495199 = 31495348
191 + 31495157 = 31495348
239 + 31495109 = 31495348
461 + 31494887 = 31495348
641 + 31494707 = 31495348
659 + 31494689 = 31495348
839 + 31494509 = 31495348

Showing the first eight; more decompositions exist.
