Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471764, here are decompositions:

53 + 31471711 = 31471764
61 + 31471703 = 31471764
67 + 31471697 = 31471764
83 + 31471681 = 31471764
97 + 31471667 = 31471764
101 + 31471663 = 31471764
127 + 31471637 = 31471764
131 + 31471633 = 31471764

Showing the first eight; more decompositions exist.
