Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8590, here are decompositions:

17 + 8573 = 8590
47 + 8543 = 8590
53 + 8537 = 8590
89 + 8501 = 8590
167 + 8423 = 8590
227 + 8363 = 8590
293 + 8297 = 8590
317 + 8273 = 8590

Showing the first eight; more decompositions exist.
