Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651018, here are decompositions:

37 + 8650981 = 8651018
139 + 8650879 = 8651018
241 + 8650777 = 8651018
331 + 8650687 = 8651018
349 + 8650669 = 8651018
367 + 8650651 = 8651018
421 + 8650597 = 8651018
457 + 8650561 = 8651018

Showing the first eight; more decompositions exist.
