Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495734, here are decompositions:

5 + 31495729 = 31495734
41 + 31495693 = 31495734
43 + 31495691 = 31495734
71 + 31495663 = 31495734
73 + 31495661 = 31495734
131 + 31495603 = 31495734
211 + 31495523 = 31495734
223 + 31495511 = 31495734

Showing the first eight; more decompositions exist.
