Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980998, here are decompositions:

41 + 980957 = 980998
89 + 980909 = 980998
101 + 980897 = 980998
167 + 980831 = 980998
197 + 980801 = 980998
269 + 980729 = 980998
281 + 980717 = 980998
311 + 980687 = 980998

Showing the first eight; more decompositions exist.
