Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737904, here are decompositions:

31 + 8737873 = 8737904
37 + 8737867 = 8737904
61 + 8737843 = 8737904
103 + 8737801 = 8737904
163 + 8737741 = 8737904
211 + 8737693 = 8737904
277 + 8737627 = 8737904
313 + 8737591 = 8737904

Showing the first eight; more decompositions exist.
