Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727122, here are decompositions:

3 + 8727119 = 8727122
13 + 8727109 = 8727122
31 + 8727091 = 8727122
73 + 8727049 = 8727122
139 + 8726983 = 8727122
199 + 8726923 = 8727122
409 + 8726713 = 8727122
601 + 8726521 = 8727122

Showing the first eight; more decompositions exist.
