Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641118, here are decompositions:

151 + 8640967 = 8641118
229 + 8640889 = 8641118
331 + 8640787 = 8641118
337 + 8640781 = 8641118
379 + 8640739 = 8641118
439 + 8640679 = 8641118
571 + 8640547 = 8641118
691 + 8640427 = 8641118

Showing the first eight; more decompositions exist.
