Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995438, here are decompositions:

7 + 995431 = 995438
61 + 995377 = 995438
97 + 995341 = 995438
109 + 995329 = 995438
211 + 995227 = 995438
271 + 995167 = 995438
571 + 994867 = 995438
601 + 994837 = 995438

Showing the first eight; more decompositions exist.
