Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737824, here are decompositions:

23 + 8737801 = 8737824
41 + 8737783 = 8737824
61 + 8737763 = 8737824
83 + 8737741 = 8737824
107 + 8737717 = 8737824
127 + 8737697 = 8737824
131 + 8737693 = 8737824
157 + 8737667 = 8737824

Showing the first eight; more decompositions exist.
