Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737730, here are decompositions:

13 + 8737717 = 8737730
31 + 8737699 = 8737730
37 + 8737693 = 8737730
61 + 8737669 = 8737730
73 + 8737657 = 8737730
103 + 8737627 = 8737730
139 + 8737591 = 8737730
229 + 8737501 = 8737730

Showing the first eight; more decompositions exist.
