Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537666, here are decompositions:

5 + 537661 = 537666
29 + 537637 = 537666
67 + 537599 = 537666
79 + 537587 = 537666
83 + 537583 = 537666
97 + 537569 = 537666
139 + 537527 = 537666
263 + 537403 = 537666

Showing the first eight; more decompositions exist.
