Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501442, here are decompositions:

23 + 501419 = 501442
41 + 501401 = 501442
59 + 501383 = 501442
101 + 501341 = 501442
233 + 501209 = 501442
239 + 501203 = 501442
251 + 501191 = 501442
269 + 501173 = 501442

Showing the first eight; more decompositions exist.
