Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618464, here are decompositions:

137 + 8618327 = 8618464
167 + 8618297 = 8618464
191 + 8618273 = 8618464
227 + 8618237 = 8618464
251 + 8618213 = 8618464
317 + 8618147 = 8618464
401 + 8618063 = 8618464
431 + 8618033 = 8618464

Showing the first eight; more decompositions exist.
