Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645948, here are decompositions:

7 + 8645941 = 8645948
61 + 8645887 = 8645948
229 + 8645719 = 8645948
331 + 8645617 = 8645948
457 + 8645491 = 8645948
499 + 8645449 = 8645948
541 + 8645407 = 8645948
607 + 8645341 = 8645948

Showing the first eight; more decompositions exist.
