Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28590, here are decompositions:

11 + 28579 = 28590
17 + 28573 = 28590
19 + 28571 = 28590
31 + 28559 = 28590
41 + 28549 = 28590
43 + 28547 = 28590
53 + 28537 = 28590
73 + 28517 = 28590

Showing the first eight; more decompositions exist.
