Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645954, here are decompositions:

13 + 8645941 = 8645954
67 + 8645887 = 8645954
151 + 8645803 = 8645954
181 + 8645773 = 8645954
193 + 8645761 = 8645954
307 + 8645647 = 8645954
337 + 8645617 = 8645954
367 + 8645587 = 8645954

Showing the first eight; more decompositions exist.
