Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987964, here are decompositions:

23 + 987941 = 987964
53 + 987911 = 987964
113 + 987851 = 987964
167 + 987797 = 987964
251 + 987713 = 987964
431 + 987533 = 987964
491 + 987473 = 987964
773 + 987191 = 987964

Showing the first eight; more decompositions exist.
