Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739290, here are decompositions:

97 + 8739193 = 8739290
103 + 8739187 = 8739290
127 + 8739163 = 8739290
163 + 8739127 = 8739290
193 + 8739097 = 8739290
211 + 8739079 = 8739290
283 + 8739007 = 8739290
409 + 8738881 = 8739290

Showing the first eight; more decompositions exist.
