Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644478, here are decompositions:

151 + 8644327 = 8644478
307 + 8644171 = 8644478
331 + 8644147 = 8644478
397 + 8644081 = 8644478
421 + 8644057 = 8644478
487 + 8643991 = 8644478
691 + 8643787 = 8644478
757 + 8643721 = 8644478

Showing the first eight; more decompositions exist.
