Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592982, here are decompositions:

11 + 31592971 = 31592982
23 + 31592959 = 31592982
59 + 31592923 = 31592982
61 + 31592921 = 31592982
139 + 31592843 = 31592982
149 + 31592833 = 31592982
173 + 31592809 = 31592982
331 + 31592651 = 31592982

Showing the first eight; more decompositions exist.
