Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501998, here are decompositions:

31 + 501967 = 501998
67 + 501931 = 501998
109 + 501889 = 501998
157 + 501841 = 501998
181 + 501817 = 501998
229 + 501769 = 501998
307 + 501691 = 501998
397 + 501601 = 501998

Showing the first eight; more decompositions exist.
