Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740218, here are decompositions:

31 + 8740187 = 8740218
61 + 8740157 = 8740218
79 + 8740139 = 8740218
89 + 8740129 = 8740218
101 + 8740117 = 8740218
107 + 8740111 = 8740218
131 + 8740087 = 8740218
181 + 8740037 = 8740218

Showing the first eight; more decompositions exist.
