Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995180, here are decompositions:

7 + 995173 = 995180
13 + 995167 = 995180
61 + 995119 = 995180
127 + 995053 = 995180
157 + 995023 = 995180
313 + 994867 = 995180
349 + 994831 = 995180
367 + 994813 = 995180

Showing the first eight; more decompositions exist.
