Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995642, here are decompositions:

19 + 995623 = 995642
31 + 995611 = 995642
103 + 995539 = 995642
181 + 995461 = 995642
199 + 995443 = 995642
211 + 995431 = 995642
313 + 995329 = 995642
523 + 995119 = 995642

Showing the first eight; more decompositions exist.
