Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649118, here are decompositions:

47 + 8649071 = 8649118
89 + 8649029 = 8649118
197 + 8648921 = 8649118
239 + 8648879 = 8649118
251 + 8648867 = 8649118
281 + 8648837 = 8649118
389 + 8648729 = 8649118
431 + 8648687 = 8649118

Showing the first eight; more decompositions exist.
