Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982138, here are decompositions:

5 + 982133 = 982138
41 + 982097 = 982138
71 + 982067 = 982138
191 + 981947 = 982138
197 + 981941 = 982138
251 + 981887 = 982138
431 + 981707 = 982138
569 + 981569 = 982138

Showing the first eight; more decompositions exist.
