Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739158, here are decompositions:

31 + 8739127 = 8739158
61 + 8739097 = 8739158
79 + 8739079 = 8739158
151 + 8739007 = 8739158
157 + 8739001 = 8739158
229 + 8738929 = 8739158
277 + 8738881 = 8739158
349 + 8738809 = 8739158

Showing the first eight; more decompositions exist.
