Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538072, here are decompositions:

23 + 538049 = 538072
53 + 538019 = 538072
71 + 538001 = 538072
131 + 537941 = 538072
173 + 537899 = 538072
461 + 537611 = 538072
503 + 537569 = 538072
659 + 537413 = 538072

Showing the first eight; more decompositions exist.
