Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981766, here are decompositions:

53 + 981713 = 981766
59 + 981707 = 981766
83 + 981683 = 981766
113 + 981653 = 981766
167 + 981599 = 981766
179 + 981587 = 981766
197 + 981569 = 981766
239 + 981527 = 981766

Showing the first eight; more decompositions exist.
