Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538042, here are decompositions:

23 + 538019 = 538042
41 + 538001 = 538042
101 + 537941 = 538042
269 + 537773 = 538042
293 + 537749 = 538042
431 + 537611 = 538042
443 + 537599 = 538042
641 + 537401 = 538042

Showing the first eight; more decompositions exist.
