Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987088, here are decompositions:

5 + 987083 = 987088
59 + 987029 = 987088
107 + 986981 = 987088
239 + 986849 = 987088
251 + 986837 = 987088
269 + 986819 = 987088
359 + 986729 = 987088
491 + 986597 = 987088

Showing the first eight; more decompositions exist.
