Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87534, here are decompositions:

11 + 87523 = 87534
17 + 87517 = 87534
23 + 87511 = 87534
43 + 87491 = 87534
53 + 87481 = 87534
61 + 87473 = 87534
101 + 87433 = 87534
107 + 87427 = 87534

Showing the first eight; more decompositions exist.
