Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998950, here are decompositions:

3 + 998947 = 998950
23 + 998927 = 998950
41 + 998909 = 998950
53 + 998897 = 998950
89 + 998861 = 998950
107 + 998843 = 998950
131 + 998819 = 998950
137 + 998813 = 998950

Showing the first eight; more decompositions exist.
