Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987736, here are decompositions:

23 + 987713 = 987736
137 + 987599 = 987736
149 + 987587 = 987736
227 + 987509 = 987736
263 + 987473 = 987736
353 + 987383 = 987736
383 + 987353 = 987736
443 + 987293 = 987736

Showing the first eight; more decompositions exist.
