Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559192, here are decompositions:

3 + 31559189 = 31559192
31 + 31559161 = 31559192
43 + 31559149 = 31559192
61 + 31559131 = 31559192
199 + 31558993 = 31559192
229 + 31558963 = 31559192
349 + 31558843 = 31559192
373 + 31558819 = 31559192

Showing the first eight; more decompositions exist.
