Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547766, here are decompositions:

17 + 31547749 = 31547766
59 + 31547707 = 31547766
73 + 31547693 = 31547766
83 + 31547683 = 31547766
137 + 31547629 = 31547766
149 + 31547617 = 31547766
157 + 31547609 = 31547766
227 + 31547539 = 31547766

Showing the first eight; more decompositions exist.
