Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495766, here are decompositions:

13 + 31495753 = 31495766
37 + 31495729 = 31495766
73 + 31495693 = 31495766
103 + 31495663 = 31495766
109 + 31495657 = 31495766
163 + 31495603 = 31495766
349 + 31495417 = 31495766
409 + 31495357 = 31495766

Showing the first eight; more decompositions exist.
