Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537990, here are decompositions:

71 + 537919 = 537990
107 + 537883 = 537990
113 + 537877 = 537990
137 + 537853 = 537990
149 + 537841 = 537990
179 + 537811 = 537990
197 + 537793 = 537990
241 + 537749 = 537990

Showing the first eight; more decompositions exist.
