Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608566, here are decompositions:

37 + 31608529 = 31608566
139 + 31608427 = 31608566
229 + 31608337 = 31608566
349 + 31608217 = 31608566
397 + 31608169 = 31608566
433 + 31608133 = 31608566
499 + 31608067 = 31608566
709 + 31607857 = 31608566

Showing the first eight; more decompositions exist.
