Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995780, here are decompositions:

43 + 995737 = 995780
61 + 995719 = 995780
67 + 995713 = 995780
103 + 995677 = 995780
139 + 995641 = 995780
157 + 995623 = 995780
193 + 995587 = 995780
229 + 995551 = 995780

Showing the first eight; more decompositions exist.
