Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981946, here are decompositions:

5 + 981941 = 981946
59 + 981887 = 981946
137 + 981809 = 981946
149 + 981797 = 981946
233 + 981713 = 981946
239 + 981707 = 981946
263 + 981683 = 981946
293 + 981653 = 981946

Showing the first eight; more decompositions exist.
