Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559650, here are decompositions:

11 + 31559639 = 31559650
113 + 31559537 = 31559650
149 + 31559501 = 31559650
179 + 31559471 = 31559650
233 + 31559417 = 31559650
431 + 31559219 = 31559650
443 + 31559207 = 31559650
461 + 31559189 = 31559650

Showing the first eight; more decompositions exist.
