Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495704, here are decompositions:

11 + 31495693 = 31495704
13 + 31495691 = 31495704
41 + 31495663 = 31495704
43 + 31495661 = 31495704
47 + 31495657 = 31495704
101 + 31495603 = 31495704
103 + 31495601 = 31495704
113 + 31495591 = 31495704

Showing the first eight; more decompositions exist.
