Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537858, here are decompositions:

5 + 537853 = 537858
11 + 537847 = 537858
17 + 537841 = 537858
47 + 537811 = 537858
71 + 537787 = 537858
89 + 537769 = 537858
109 + 537749 = 537858
149 + 537709 = 537858

Showing the first eight; more decompositions exist.
