Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646018, here are decompositions:

37 + 8645981 = 8646018
47 + 8645971 = 8646018
131 + 8645887 = 8646018
229 + 8645789 = 8646018
257 + 8645761 = 8646018
331 + 8645687 = 8646018
349 + 8645669 = 8646018
401 + 8645617 = 8646018

Showing the first eight; more decompositions exist.
