Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737620, here are decompositions:

29 + 8737591 = 8737620
37 + 8737583 = 8737620
43 + 8737577 = 8737620
97 + 8737523 = 8737620
131 + 8737489 = 8737620
137 + 8737483 = 8737620
139 + 8737481 = 8737620
167 + 8737453 = 8737620

Showing the first eight; more decompositions exist.
