Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719382, here are decompositions:

3 + 8719379 = 8719382
79 + 8719303 = 8719382
109 + 8719273 = 8719382
163 + 8719219 = 8719382
223 + 8719159 = 8719382
241 + 8719141 = 8719382
283 + 8719099 = 8719382
379 + 8719003 = 8719382

Showing the first eight; more decompositions exist.
