Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995558, here are decompositions:

7 + 995551 = 995558
19 + 995539 = 995558
97 + 995461 = 995558
127 + 995431 = 995558
181 + 995377 = 995558
211 + 995347 = 995558
229 + 995329 = 995558
331 + 995227 = 995558

Showing the first eight; more decompositions exist.
