Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644126, here are decompositions:

3 + 8644123 = 8644126
107 + 8644019 = 8644126
167 + 8643959 = 8644126
173 + 8643953 = 8644126
233 + 8643893 = 8644126
347 + 8643779 = 8644126
419 + 8643707 = 8644126
479 + 8643647 = 8644126

Showing the first eight; more decompositions exist.
