Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559082, here are decompositions:

11 + 31559071 = 31559082
13 + 31559069 = 31559082
31 + 31559051 = 31559082
89 + 31558993 = 31559082
109 + 31558973 = 31559082
199 + 31558883 = 31559082
223 + 31558859 = 31559082
239 + 31558843 = 31559082

Showing the first eight; more decompositions exist.
