Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730672, here are decompositions:

11 + 8730661 = 8730672
23 + 8730649 = 8730672
43 + 8730629 = 8730672
53 + 8730619 = 8730672
61 + 8730611 = 8730672
89 + 8730583 = 8730672
113 + 8730559 = 8730672
199 + 8730473 = 8730672

Showing the first eight; more decompositions exist.
