Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87590, here are decompositions:

3 + 87587 = 87590
7 + 87583 = 87590
31 + 87559 = 87590
37 + 87553 = 87590
43 + 87547 = 87590
67 + 87523 = 87590
73 + 87517 = 87590
79 + 87511 = 87590

Showing the first eight; more decompositions exist.
