Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664158, here are decompositions:

199 + 8663959 = 8664158
331 + 8663827 = 8664158
337 + 8663821 = 8664158
439 + 8663719 = 8664158
457 + 8663701 = 8664158
661 + 8663497 = 8664158
691 + 8663467 = 8664158
757 + 8663401 = 8664158

Showing the first eight; more decompositions exist.
