Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84442, here are decompositions:

5 + 84437 = 84442
11 + 84431 = 84442
41 + 84401 = 84442
53 + 84389 = 84442
179 + 84263 = 84442
251 + 84191 = 84442
263 + 84179 = 84442
311 + 84131 = 84442

Showing the first eight; more decompositions exist.
