Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559604, here are decompositions:

31 + 31559573 = 31559604
67 + 31559537 = 31559604
103 + 31559501 = 31559604
137 + 31559467 = 31559604
157 + 31559447 = 31559604
191 + 31559413 = 31559604
233 + 31559371 = 31559604
283 + 31559321 = 31559604

Showing the first eight; more decompositions exist.
