Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717378, here are decompositions:

37 + 8717341 = 8717378
139 + 8717239 = 8717378
337 + 8717041 = 8717378
367 + 8717011 = 8717378
379 + 8716999 = 8717378
421 + 8716957 = 8717378
487 + 8716891 = 8717378
619 + 8716759 = 8717378

Showing the first eight; more decompositions exist.
