Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740266, here are decompositions:

47 + 8740219 = 8740266
79 + 8740187 = 8740266
83 + 8740183 = 8740266
97 + 8740169 = 8740266
103 + 8740163 = 8740266
109 + 8740157 = 8740266
127 + 8740139 = 8740266
137 + 8740129 = 8740266

Showing the first eight; more decompositions exist.
