Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740230, here are decompositions:

11 + 8740219 = 8740230
43 + 8740187 = 8740230
47 + 8740183 = 8740230
61 + 8740169 = 8740230
67 + 8740163 = 8740230
73 + 8740157 = 8740230
101 + 8740129 = 8740230
113 + 8740117 = 8740230

Showing the first eight; more decompositions exist.
