Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628530, here are decompositions:

37 + 8628493 = 8628530
67 + 8628463 = 8628530
109 + 8628421 = 8628530
181 + 8628349 = 8628530
349 + 8628181 = 8628530
373 + 8628157 = 8628530
409 + 8628121 = 8628530
433 + 8628097 = 8628530

Showing the first eight; more decompositions exist.
