Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42446, here are decompositions:

3 + 42443 = 42446
13 + 42433 = 42446
37 + 42409 = 42446
43 + 42403 = 42446
67 + 42379 = 42446
73 + 42373 = 42446
97 + 42349 = 42446
109 + 42337 = 42446

Showing the first eight; more decompositions exist.
