Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42546, here are decompositions:

13 + 42533 = 42546
37 + 42509 = 42546
47 + 42499 = 42546
59 + 42487 = 42546
73 + 42473 = 42546
79 + 42467 = 42546
83 + 42463 = 42546
89 + 42457 = 42546

Showing the first eight; more decompositions exist.
