Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720924, here are decompositions:

13 + 8720911 = 8720924
127 + 8720797 = 8720924
151 + 8720773 = 8720924
211 + 8720713 = 8720924
307 + 8720617 = 8720924
367 + 8720557 = 8720924
577 + 8720347 = 8720924
607 + 8720317 = 8720924

Showing the first eight; more decompositions exist.
