Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537918, here are decompositions:

5 + 537913 = 537918
19 + 537899 = 537918
41 + 537877 = 537918
71 + 537847 = 537918
107 + 537811 = 537918
131 + 537787 = 537918
137 + 537781 = 537918
149 + 537769 = 537918

Showing the first eight; more decompositions exist.
