Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641914, here are decompositions:

5 + 8641909 = 8641914
23 + 8641891 = 8641914
31 + 8641883 = 8641914
41 + 8641873 = 8641914
97 + 8641817 = 8641914
107 + 8641807 = 8641914
131 + 8641783 = 8641914
167 + 8641747 = 8641914

Showing the first eight; more decompositions exist.
