Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42584, here are decompositions:

7 + 42577 = 42584
13 + 42571 = 42584
97 + 42487 = 42584
127 + 42457 = 42584
151 + 42433 = 42584
181 + 42403 = 42584
193 + 42391 = 42584
211 + 42373 = 42584

Showing the first eight; more decompositions exist.
