Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704142, here are decompositions:

19 + 8704123 = 8704142
199 + 8703943 = 8704142
283 + 8703859 = 8704142
313 + 8703829 = 8704142
331 + 8703811 = 8704142
523 + 8703619 = 8704142
619 + 8703523 = 8704142
631 + 8703511 = 8704142

Showing the first eight; more decompositions exist.
