Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719418, here are decompositions:

157 + 8719261 = 8719418
199 + 8719219 = 8719418
241 + 8719177 = 8719418
277 + 8719141 = 8719418
397 + 8719021 = 8719418
541 + 8718877 = 8719418
607 + 8718811 = 8719418
619 + 8718799 = 8719418

Showing the first eight; more decompositions exist.
