Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737884, here are decompositions:

11 + 8737873 = 8737884
13 + 8737871 = 8737884
17 + 8737867 = 8737884
41 + 8737843 = 8737884
83 + 8737801 = 8737884
101 + 8737783 = 8737884
167 + 8737717 = 8737884
191 + 8737693 = 8737884

Showing the first eight; more decompositions exist.
