Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724916, here are decompositions:

89 + 8724827 = 8724916
113 + 8724803 = 8724916
197 + 8724719 = 8724916
419 + 8724497 = 8724916
449 + 8724467 = 8724916
479 + 8724437 = 8724916
569 + 8724347 = 8724916
587 + 8724329 = 8724916

Showing the first eight; more decompositions exist.
