Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644974, here are decompositions:

11 + 8644963 = 8644974
17 + 8644957 = 8644974
47 + 8644927 = 8644974
61 + 8644913 = 8644974
71 + 8644903 = 8644974
101 + 8644873 = 8644974
113 + 8644861 = 8644974
131 + 8644843 = 8644974

Showing the first eight; more decompositions exist.
