Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42494, here are decompositions:

3 + 42491 = 42494
7 + 42487 = 42494
31 + 42463 = 42494
37 + 42457 = 42494
43 + 42451 = 42494
61 + 42433 = 42494
97 + 42397 = 42494
103 + 42391 = 42494

Showing the first eight; more decompositions exist.
