Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537690, here are decompositions:

11 + 537679 = 537690
17 + 537673 = 537690
29 + 537661 = 537690
53 + 537637 = 537690
79 + 537611 = 537690
103 + 537587 = 537690
107 + 537583 = 537690
163 + 537527 = 537690

Showing the first eight; more decompositions exist.
