Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740188, here are decompositions:

5 + 8740183 = 8740188
19 + 8740169 = 8740188
31 + 8740157 = 8740188
59 + 8740129 = 8740188
71 + 8740117 = 8740188
101 + 8740087 = 8740188
151 + 8740037 = 8740188
227 + 8739961 = 8740188

Showing the first eight; more decompositions exist.
