Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727818, here are decompositions:

61 + 8727757 = 8727818
199 + 8727619 = 8727818
241 + 8727577 = 8727818
367 + 8727451 = 8727818
571 + 8727247 = 8727818
607 + 8727211 = 8727818
661 + 8727157 = 8727818
709 + 8727109 = 8727818

Showing the first eight; more decompositions exist.
