Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537728, here are decompositions:

19 + 537709 = 537728
67 + 537661 = 537728
181 + 537547 = 537728
349 + 537379 = 537728
397 + 537331 = 537728
421 + 537307 = 537728
487 + 537241 = 537728
547 + 537181 = 537728

Showing the first eight; more decompositions exist.
