Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987718, here are decompositions:

5 + 987713 = 987718
59 + 987659 = 987718
131 + 987587 = 987718
227 + 987491 = 987718
419 + 987299 = 987718
467 + 987251 = 987718
491 + 987227 = 987718
509 + 987209 = 987718

Showing the first eight; more decompositions exist.
