Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87486, here are decompositions:

5 + 87481 = 87486
13 + 87473 = 87486
43 + 87443 = 87486
53 + 87433 = 87486
59 + 87427 = 87486
79 + 87407 = 87486
83 + 87403 = 87486
103 + 87383 = 87486

Showing the first eight; more decompositions exist.
