Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737980, here are decompositions:

37 + 8737943 = 8737980
47 + 8737933 = 8737980
59 + 8737921 = 8737980
107 + 8737873 = 8737980
109 + 8737871 = 8737980
113 + 8737867 = 8737980
131 + 8737849 = 8737980
137 + 8737843 = 8737980

Showing the first eight; more decompositions exist.
