Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537018, here are decompositions:

7 + 537011 = 537018
11 + 537007 = 537018
17 + 537001 = 537018
19 + 536999 = 537018
29 + 536989 = 537018
47 + 536971 = 537018
71 + 536947 = 537018
89 + 536929 = 537018

Showing the first eight; more decompositions exist.
