Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501398, here are decompositions:

31 + 501367 = 501398
127 + 501271 = 501398
181 + 501217 = 501398
211 + 501187 = 501398
241 + 501157 = 501398
277 + 501121 = 501398
367 + 501031 = 501398
379 + 501019 = 501398

Showing the first eight; more decompositions exist.
