Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644412, here are decompositions:

151 + 8644261 = 8644412
181 + 8644231 = 8644412
199 + 8644213 = 8644412
241 + 8644171 = 8644412
331 + 8644081 = 8644412
421 + 8643991 = 8644412
523 + 8643889 = 8644412
691 + 8643721 = 8644412

Showing the first eight; more decompositions exist.
