Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495706, here are decompositions:

13 + 31495693 = 31495706
43 + 31495663 = 31495706
103 + 31495603 = 31495706
283 + 31495423 = 31495706
349 + 31495357 = 31495706
373 + 31495333 = 31495706
433 + 31495273 = 31495706
643 + 31495063 = 31495706

Showing the first eight; more decompositions exist.
