Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740210, here are decompositions:

23 + 8740187 = 8740210
41 + 8740169 = 8740210
47 + 8740163 = 8740210
53 + 8740157 = 8740210
71 + 8740139 = 8740210
113 + 8740097 = 8740210
173 + 8740037 = 8740210
257 + 8739953 = 8740210

Showing the first eight; more decompositions exist.
