Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543052, here are decompositions:

43 + 31543009 = 31543052
61 + 31542991 = 31543052
103 + 31542949 = 31543052
109 + 31542943 = 31543052
223 + 31542829 = 31543052
241 + 31542811 = 31543052
349 + 31542703 = 31543052
421 + 31542631 = 31543052

Showing the first eight; more decompositions exist.
