Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644148, here are decompositions:

67 + 8644081 = 8644148
151 + 8643997 = 8644148
157 + 8643991 = 8644148
229 + 8643919 = 8644148
571 + 8643577 = 8644148
661 + 8643487 = 8644148
691 + 8643457 = 8644148
739 + 8643409 = 8644148

Showing the first eight; more decompositions exist.
