Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142584, here are decompositions:

11 + 142573 = 142584
17 + 142567 = 142584
31 + 142553 = 142584
37 + 142547 = 142584
41 + 142543 = 142584
47 + 142537 = 142584
83 + 142501 = 142584
131 + 142453 = 142584

Showing the first eight; more decompositions exist.
