Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981082, here are decompositions:

5 + 981077 = 981082
59 + 981023 = 981082
71 + 981011 = 981082
83 + 980999 = 981082
173 + 980909 = 981082
251 + 980831 = 981082
281 + 980801 = 981082
353 + 980729 = 981082

Showing the first eight; more decompositions exist.
