Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691946, here are decompositions:

5 + 8691941 = 8691946
23 + 8691923 = 8691946
113 + 8691833 = 8691946
257 + 8691689 = 8691946
293 + 8691653 = 8691946
353 + 8691593 = 8691946
359 + 8691587 = 8691946
449 + 8691497 = 8691946

Showing the first eight; more decompositions exist.
