Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 547142, here are decompositions:

3 + 547139 = 547142
181 + 546961 = 547142
199 + 546943 = 547142
223 + 546919 = 547142
283 + 546859 = 547142
433 + 546709 = 547142
499 + 546643 = 547142
523 + 546619 = 547142

Showing the first eight; more decompositions exist.
