Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987568, here are decompositions:

59 + 987509 = 987568
269 + 987299 = 987568
317 + 987251 = 987568
359 + 987209 = 987568
467 + 987101 = 987568
479 + 987089 = 987568
587 + 986981 = 987568
641 + 986927 = 987568

Showing the first eight; more decompositions exist.
