Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981112, here are decompositions:

89 + 981023 = 981112
101 + 981011 = 981112
113 + 980999 = 981112
149 + 980963 = 981112
191 + 980921 = 981112
281 + 980831 = 981112
311 + 980801 = 981112
383 + 980729 = 981112

Showing the first eight; more decompositions exist.
