Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495702, here are decompositions:

11 + 31495691 = 31495702
41 + 31495661 = 31495702
101 + 31495601 = 31495702
113 + 31495589 = 31495702
179 + 31495523 = 31495702
191 + 31495511 = 31495702
233 + 31495469 = 31495702
239 + 31495463 = 31495702

Showing the first eight; more decompositions exist.
