Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42450, here are decompositions:

7 + 42443 = 42450
13 + 42437 = 42450
17 + 42433 = 42450
41 + 42409 = 42450
43 + 42407 = 42450
47 + 42403 = 42450
53 + 42397 = 42450
59 + 42391 = 42450

Showing the first eight; more decompositions exist.
