Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486794, here are decompositions:

43 + 31486751 = 31486794
61 + 31486733 = 31486794
67 + 31486727 = 31486794
71 + 31486723 = 31486794
83 + 31486711 = 31486794
137 + 31486657 = 31486794
151 + 31486643 = 31486794
167 + 31486627 = 31486794

Showing the first eight; more decompositions exist.
