Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740140, here are decompositions:

11 + 8740129 = 8740140
23 + 8740117 = 8740140
29 + 8740111 = 8740140
43 + 8740097 = 8740140
53 + 8740087 = 8740140
103 + 8740037 = 8740140
137 + 8740003 = 8740140
173 + 8739967 = 8740140

Showing the first eight; more decompositions exist.
