Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667650, here are decompositions:

37 + 8667613 = 8667650
139 + 8667511 = 8667650
193 + 8667457 = 8667650
223 + 8667427 = 8667650
331 + 8667319 = 8667650
337 + 8667313 = 8667650
349 + 8667301 = 8667650
379 + 8667271 = 8667650

Showing the first eight; more decompositions exist.
