Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981124, here are decompositions:

47 + 981077 = 981124
101 + 981023 = 981124
107 + 981017 = 981124
113 + 981011 = 981124
167 + 980957 = 981124
227 + 980897 = 981124
293 + 980831 = 981124
503 + 980621 = 981124

Showing the first eight; more decompositions exist.
