Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618534, here are decompositions:

157 + 8618377 = 8618534
241 + 8618293 = 8618534
277 + 8618257 = 8618534
283 + 8618251 = 8618534
313 + 8618221 = 8618534
487 + 8618047 = 8618534
541 + 8617993 = 8618534
601 + 8617933 = 8618534

Showing the first eight; more decompositions exist.
