Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559092, here are decompositions:

11 + 31559081 = 31559092
23 + 31559069 = 31559092
41 + 31559051 = 31559092
233 + 31558859 = 31559092
269 + 31558823 = 31559092
293 + 31558799 = 31559092
359 + 31558733 = 31559092
419 + 31558673 = 31559092

Showing the first eight; more decompositions exist.
