Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534112, here are decompositions:

61 + 31534051 = 31534112
79 + 31534033 = 31534112
163 + 31533949 = 31534112
193 + 31533919 = 31534112
241 + 31533871 = 31534112
283 + 31533829 = 31534112
349 + 31533763 = 31534112
499 + 31533613 = 31534112

Showing the first eight; more decompositions exist.
