Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737530, here are decompositions:

7 + 8737523 = 8737530
29 + 8737501 = 8737530
41 + 8737489 = 8737530
47 + 8737483 = 8737530
71 + 8737459 = 8737530
97 + 8737433 = 8737530
103 + 8737427 = 8737530
107 + 8737423 = 8737530

Showing the first eight; more decompositions exist.
