Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987772, here are decompositions:

59 + 987713 = 987772
113 + 987659 = 987772
173 + 987599 = 987772
179 + 987593 = 987772
239 + 987533 = 987772
263 + 987509 = 987772
281 + 987491 = 987772
389 + 987383 = 987772

Showing the first eight; more decompositions exist.
