Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995580, here are decompositions:

7 + 995573 = 995580
13 + 995567 = 995580
29 + 995551 = 995580
31 + 995549 = 995580
41 + 995539 = 995580
67 + 995513 = 995580
109 + 995471 = 995580
137 + 995443 = 995580

Showing the first eight; more decompositions exist.
