Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719442, here are decompositions:

139 + 8719303 = 8719442
181 + 8719261 = 8719442
223 + 8719219 = 8719442
229 + 8719213 = 8719442
283 + 8719159 = 8719442
421 + 8719021 = 8719442
439 + 8719003 = 8719442
619 + 8718823 = 8719442

Showing the first eight; more decompositions exist.
