Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592856, here are decompositions:

7 + 31592849 = 31592856
13 + 31592843 = 31592856
23 + 31592833 = 31592856
47 + 31592809 = 31592856
59 + 31592797 = 31592856
83 + 31592773 = 31592856
109 + 31592747 = 31592856
173 + 31592683 = 31592856

Showing the first eight; more decompositions exist.
