Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501430, here are decompositions:

3 + 501427 = 501430
11 + 501419 = 501430
29 + 501401 = 501430
47 + 501383 = 501430
89 + 501341 = 501430
113 + 501317 = 501430
131 + 501299 = 501430
173 + 501257 = 501430

Showing the first eight; more decompositions exist.
