Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42402, here are decompositions:

5 + 42397 = 42402
11 + 42391 = 42402
23 + 42379 = 42402
29 + 42373 = 42402
43 + 42359 = 42402
53 + 42349 = 42402
71 + 42331 = 42402
79 + 42323 = 42402

Showing the first eight; more decompositions exist.
