Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647954, here are decompositions:

5 + 8647949 = 8647954
17 + 8647937 = 8647954
41 + 8647913 = 8647954
131 + 8647823 = 8647954
137 + 8647817 = 8647954
257 + 8647697 = 8647954
443 + 8647511 = 8647954
563 + 8647391 = 8647954

Showing the first eight; more decompositions exist.
