Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558014, here are decompositions:

17 + 31557997 = 31558014
31 + 31557983 = 31558014
43 + 31557971 = 31558014
53 + 31557961 = 31558014
83 + 31557931 = 31558014
157 + 31557857 = 31558014
181 + 31557833 = 31558014
223 + 31557791 = 31558014

Showing the first eight; more decompositions exist.
