Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986250, here are decompositions:

11 + 986239 = 986250
37 + 986213 = 986250
43 + 986207 = 986250
53 + 986197 = 986250
59 + 986191 = 986250
61 + 986189 = 986250
73 + 986177 = 986250
101 + 986149 = 986250

Showing the first eight; more decompositions exist.
