Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42444, here are decompositions:

7 + 42437 = 42444
11 + 42433 = 42444
37 + 42407 = 42444
41 + 42403 = 42444
47 + 42397 = 42444
53 + 42391 = 42444
71 + 42373 = 42444
107 + 42337 = 42444

Showing the first eight; more decompositions exist.
