Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559422, here are decompositions:

5 + 31559417 = 31559422
71 + 31559351 = 31559422
101 + 31559321 = 31559422
233 + 31559189 = 31559422
353 + 31559069 = 31559422
449 + 31558973 = 31559422
563 + 31558859 = 31559422
599 + 31558823 = 31559422

Showing the first eight; more decompositions exist.
