Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730732, here are decompositions:

41 + 8730691 = 8730732
71 + 8730661 = 8730732
83 + 8730649 = 8730732
103 + 8730629 = 8730732
113 + 8730619 = 8730732
149 + 8730583 = 8730732
173 + 8730559 = 8730732
379 + 8730353 = 8730732

Showing the first eight; more decompositions exist.
