Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559524, here are decompositions:

23 + 31559501 = 31559524
53 + 31559471 = 31559524
107 + 31559417 = 31559524
173 + 31559351 = 31559524
317 + 31559207 = 31559524
431 + 31559093 = 31559524
443 + 31559081 = 31559524
641 + 31558883 = 31559524

Showing the first eight; more decompositions exist.
