Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684738, here are decompositions:

109 + 8684629 = 8684738
151 + 8684587 = 8684738
277 + 8684461 = 8684738
331 + 8684407 = 8684738
379 + 8684359 = 8684738
397 + 8684341 = 8684738
409 + 8684329 = 8684738
607 + 8684131 = 8684738

Showing the first eight; more decompositions exist.
