Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88640, here are decompositions:

31 + 88609 = 88640
127 + 88513 = 88640
229 + 88411 = 88640
313 + 88327 = 88640
379 + 88261 = 88640
463 + 88177 = 88640
523 + 88117 = 88640
547 + 88093 = 88640

Showing the first eight; more decompositions exist.
