Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644120, here are decompositions:

29 + 8644091 = 8644120
59 + 8644061 = 8644120
71 + 8644049 = 8644120
101 + 8644019 = 8644120
167 + 8643953 = 8644120
179 + 8643941 = 8644120
197 + 8643923 = 8644120
227 + 8643893 = 8644120

Showing the first eight; more decompositions exist.
