Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608632, here are decompositions:

43 + 31608589 = 31608632
103 + 31608529 = 31608632
151 + 31608481 = 31608632
283 + 31608349 = 31608632
313 + 31608319 = 31608632
331 + 31608301 = 31608632
463 + 31608169 = 31608632
499 + 31608133 = 31608632

Showing the first eight; more decompositions exist.
