Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536840, here are decompositions:

37 + 536803 = 536840
61 + 536779 = 536840
67 + 536773 = 536840
97 + 536743 = 536840
163 + 536677 = 536840
277 + 536563 = 536840
307 + 536533 = 536840
331 + 536509 = 536840

Showing the first eight; more decompositions exist.
