Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537816, here are decompositions:

5 + 537811 = 537816
23 + 537793 = 537816
29 + 537787 = 537816
43 + 537773 = 537816
47 + 537769 = 537816
67 + 537749 = 537816
73 + 537743 = 537816
107 + 537709 = 537816

Showing the first eight; more decompositions exist.
