Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559434, here are decompositions:

17 + 31559417 = 31559434
83 + 31559351 = 31559434
113 + 31559321 = 31559434
227 + 31559207 = 31559434
353 + 31559081 = 31559434
383 + 31559051 = 31559434
461 + 31558973 = 31559434
587 + 31558847 = 31559434

Showing the first eight; more decompositions exist.
