Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486734, here are decompositions:

7 + 31486727 = 31486734
11 + 31486723 = 31486734
23 + 31486711 = 31486734
73 + 31486661 = 31486734
101 + 31486633 = 31486734
107 + 31486627 = 31486734
131 + 31486603 = 31486734
163 + 31486571 = 31486734

Showing the first eight; more decompositions exist.
