Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987922, here are decompositions:

11 + 987911 = 987922
53 + 987869 = 987922
71 + 987851 = 987922
101 + 987821 = 987922
113 + 987809 = 987922
263 + 987659 = 987922
389 + 987533 = 987922
431 + 987491 = 987922

Showing the first eight; more decompositions exist.
