Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537840, here are decompositions:

29 + 537811 = 537840
47 + 537793 = 537840
53 + 537787 = 537840
59 + 537781 = 537840
67 + 537773 = 537840
71 + 537769 = 537840
97 + 537743 = 537840
101 + 537739 = 537840

Showing the first eight; more decompositions exist.
