Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987532, here are decompositions:

23 + 987509 = 987532
41 + 987491 = 987532
59 + 987473 = 987532
149 + 987383 = 987532
179 + 987353 = 987532
233 + 987299 = 987532
239 + 987293 = 987532
281 + 987251 = 987532

Showing the first eight; more decompositions exist.
