Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501626, here are decompositions:

3 + 501623 = 501626
163 + 501463 = 501626
199 + 501427 = 501626
283 + 501343 = 501626
397 + 501229 = 501626
409 + 501217 = 501626
439 + 501187 = 501626
487 + 501139 = 501626

Showing the first eight; more decompositions exist.
