Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724826, here are decompositions:

23 + 8724803 = 8724826
107 + 8724719 = 8724826
113 + 8724713 = 8724826
347 + 8724479 = 8724826
359 + 8724467 = 8724826
389 + 8724437 = 8724826
449 + 8724377 = 8724826
479 + 8724347 = 8724826

Showing the first eight; more decompositions exist.
