Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559234, here are decompositions:

73 + 31559161 = 31559234
103 + 31559131 = 31559234
163 + 31559071 = 31559234
241 + 31558993 = 31559234
271 + 31558963 = 31559234
277 + 31558957 = 31559234
307 + 31558927 = 31559234
337 + 31558897 = 31559234

Showing the first eight; more decompositions exist.
