Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737520, here are decompositions:

19 + 8737501 = 8737520
31 + 8737489 = 8737520
37 + 8737483 = 8737520
61 + 8737459 = 8737520
67 + 8737453 = 8737520
97 + 8737423 = 8737520
163 + 8737357 = 8737520
271 + 8737249 = 8737520

Showing the first eight; more decompositions exist.
