Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495674, here are decompositions:

11 + 31495663 = 31495674
13 + 31495661 = 31495674
17 + 31495657 = 31495674
71 + 31495603 = 31495674
73 + 31495601 = 31495674
83 + 31495591 = 31495674
151 + 31495523 = 31495674
157 + 31495517 = 31495674

Showing the first eight; more decompositions exist.
