Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986144, here are decompositions:

7 + 986137 = 986144
13 + 986131 = 986144
31 + 986113 = 986144
43 + 986101 = 986144
73 + 986071 = 986144
97 + 986047 = 986144
151 + 985993 = 986144
163 + 985981 = 986144

Showing the first eight; more decompositions exist.
