Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987562, here are decompositions:

3 + 987559 = 987562
29 + 987533 = 987562
53 + 987509 = 987562
71 + 987491 = 987562
89 + 987473 = 987562
179 + 987383 = 987562
263 + 987299 = 987562
269 + 987293 = 987562

Showing the first eight; more decompositions exist.
