Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28442, here are decompositions:

3 + 28439 = 28442
13 + 28429 = 28442
31 + 28411 = 28442
163 + 28279 = 28442
223 + 28219 = 28442
241 + 28201 = 28442
331 + 28111 = 28442
373 + 28069 = 28442

Showing the first eight; more decompositions exist.
