Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752142, here are decompositions:

13 + 8752129 = 8752142
19 + 8752123 = 8752142
79 + 8752063 = 8752142
103 + 8752039 = 8752142
109 + 8752033 = 8752142
193 + 8751949 = 8752142
211 + 8751931 = 8752142
271 + 8751871 = 8752142

Showing the first eight; more decompositions exist.
