Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574760, here are decompositions:

13 + 31574747 = 31574760
37 + 31574723 = 31574760
59 + 31574701 = 31574760
67 + 31574693 = 31574760
71 + 31574689 = 31574760
73 + 31574687 = 31574760
79 + 31574681 = 31574760
83 + 31574677 = 31574760

Showing the first eight; more decompositions exist.
