Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547760, here are decompositions:

11 + 31547749 = 31547760
29 + 31547731 = 31547760
53 + 31547707 = 31547760
59 + 31547701 = 31547760
67 + 31547693 = 31547760
89 + 31547671 = 31547760
131 + 31547629 = 31547760
151 + 31547609 = 31547760

Showing the first eight; more decompositions exist.
