Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995578, here are decompositions:

5 + 995573 = 995578
11 + 995567 = 995578
29 + 995549 = 995578
47 + 995531 = 995578
107 + 995471 = 995578
131 + 995447 = 995578
179 + 995399 = 995578
191 + 995387 = 995578

Showing the first eight; more decompositions exist.
