Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87612, here are decompositions:

23 + 87589 = 87612
29 + 87583 = 87612
53 + 87559 = 87612
59 + 87553 = 87612
71 + 87541 = 87612
73 + 87539 = 87612
89 + 87523 = 87612
101 + 87511 = 87612

Showing the first eight; more decompositions exist.
