Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87450, here are decompositions:

7 + 87443 = 87450
17 + 87433 = 87450
23 + 87427 = 87450
29 + 87421 = 87450
43 + 87407 = 87450
47 + 87403 = 87450
67 + 87383 = 87450
113 + 87337 = 87450

Showing the first eight; more decompositions exist.
