Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608626, here are decompositions:

37 + 31608589 = 31608626
97 + 31608529 = 31608626
199 + 31608427 = 31608626
277 + 31608349 = 31608626
307 + 31608319 = 31608626
409 + 31608217 = 31608626
457 + 31608169 = 31608626
463 + 31608163 = 31608626

Showing the first eight; more decompositions exist.
