Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737812, here are decompositions:

11 + 8737801 = 8737812
23 + 8737789 = 8737812
29 + 8737783 = 8737812
71 + 8737741 = 8737812
103 + 8737709 = 8737812
113 + 8737699 = 8737812
229 + 8737583 = 8737812
241 + 8737571 = 8737812

Showing the first eight; more decompositions exist.
