Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981934, here are decompositions:

47 + 981887 = 981934
137 + 981797 = 981934
227 + 981707 = 981934
251 + 981683 = 981934
281 + 981653 = 981934
311 + 981623 = 981934
347 + 981587 = 981934
461 + 981473 = 981934

Showing the first eight; more decompositions exist.
