Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628698, here are decompositions:

37 + 8628661 = 8628698
97 + 8628601 = 8628698
151 + 8628547 = 8628698
277 + 8628421 = 8628698
349 + 8628349 = 8628698
541 + 8628157 = 8628698
577 + 8628121 = 8628698
601 + 8628097 = 8628698

Showing the first eight; more decompositions exist.
