Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559244, here are decompositions:

5 + 31559239 = 31559244
37 + 31559207 = 31559244
83 + 31559161 = 31559244
113 + 31559131 = 31559244
151 + 31559093 = 31559244
163 + 31559081 = 31559244
173 + 31559071 = 31559244
193 + 31559051 = 31559244

Showing the first eight; more decompositions exist.
