Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981058, here are decompositions:

41 + 981017 = 981058
47 + 981011 = 981058
59 + 980999 = 981058
101 + 980957 = 981058
137 + 980921 = 981058
149 + 980909 = 981058
227 + 980831 = 981058
257 + 980801 = 981058

Showing the first eight; more decompositions exist.
