Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007642, here are decompositions:

43 + 1007599 = 1007642
241 + 1007401 = 1007642
283 + 1007359 = 1007642
439 + 1007203 = 1007642
463 + 1007179 = 1007642
523 + 1007119 = 1007642
619 + 1007023 = 1007642
673 + 1006969 = 1007642

Showing the first eight; more decompositions exist.
