Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84940, here are decompositions:

71 + 84869 = 84940
83 + 84857 = 84940
113 + 84827 = 84940
131 + 84809 = 84940
179 + 84761 = 84940
227 + 84713 = 84940
239 + 84701 = 84940
281 + 84659 = 84940

Showing the first eight; more decompositions exist.
