Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719328, here are decompositions:

67 + 8719261 = 8719328
109 + 8719219 = 8719328
151 + 8719177 = 8719328
229 + 8719099 = 8719328
271 + 8719057 = 8719328
307 + 8719021 = 8719328
379 + 8718949 = 8719328
421 + 8718907 = 8719328

Showing the first eight; more decompositions exist.
