Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87560, here are decompositions:

3 + 87557 = 87560
7 + 87553 = 87560
13 + 87547 = 87560
19 + 87541 = 87560
37 + 87523 = 87560
43 + 87517 = 87560
79 + 87481 = 87560
127 + 87433 = 87560

Showing the first eight; more decompositions exist.
