Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559590, here are decompositions:

17 + 31559573 = 31559590
53 + 31559537 = 31559590
89 + 31559501 = 31559590
173 + 31559417 = 31559590
239 + 31559351 = 31559590
269 + 31559321 = 31559590
383 + 31559207 = 31559590
401 + 31559189 = 31559590

Showing the first eight; more decompositions exist.
