Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737220, here are decompositions:

43 + 8737177 = 8737220
67 + 8737153 = 8737220
103 + 8737117 = 8737220
109 + 8737111 = 8737220
157 + 8737063 = 8737220
181 + 8737039 = 8737220
199 + 8737021 = 8737220
277 + 8736943 = 8737220

Showing the first eight; more decompositions exist.
