Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99640, here are decompositions:

17 + 99623 = 99640
29 + 99611 = 99640
59 + 99581 = 99640
89 + 99551 = 99640
113 + 99527 = 99640
239 + 99401 = 99640
263 + 99377 = 99640
269 + 99371 = 99640

Showing the first eight; more decompositions exist.
