Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559392, here are decompositions:

41 + 31559351 = 31559392
71 + 31559321 = 31559392
173 + 31559219 = 31559392
311 + 31559081 = 31559392
419 + 31558973 = 31559392
509 + 31558883 = 31559392
569 + 31558823 = 31559392
593 + 31558799 = 31559392

Showing the first eight; more decompositions exist.
