Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737490, here are decompositions:

7 + 8737483 = 8737490
31 + 8737459 = 8737490
37 + 8737453 = 8737490
67 + 8737423 = 8737490
241 + 8737249 = 8737490
313 + 8737177 = 8737490
337 + 8737153 = 8737490
373 + 8737117 = 8737490

Showing the first eight; more decompositions exist.
