Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608590, here are decompositions:

3 + 31608587 = 31608590
61 + 31608529 = 31608590
109 + 31608481 = 31608590
163 + 31608427 = 31608590
241 + 31608349 = 31608590
271 + 31608319 = 31608590
373 + 31608217 = 31608590
421 + 31608169 = 31608590

Showing the first eight; more decompositions exist.
