Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995228, here are decompositions:

61 + 995167 = 995228
109 + 995119 = 995228
349 + 994879 = 995228
397 + 994831 = 995228
571 + 994657 = 995228
607 + 994621 = 995228
727 + 994501 = 995228
739 + 994489 = 995228

Showing the first eight; more decompositions exist.
