Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740158, here are decompositions:

19 + 8740139 = 8740158
29 + 8740129 = 8740158
41 + 8740117 = 8740158
47 + 8740111 = 8740158
61 + 8740097 = 8740158
71 + 8740087 = 8740158
191 + 8739967 = 8740158
197 + 8739961 = 8740158

Showing the first eight; more decompositions exist.
