Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608612, here are decompositions:

23 + 31608589 = 31608612
83 + 31608529 = 31608612
131 + 31608481 = 31608612
163 + 31608449 = 31608612
263 + 31608349 = 31608612
271 + 31608341 = 31608612
293 + 31608319 = 31608612
311 + 31608301 = 31608612

Showing the first eight; more decompositions exist.
