Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537180, here are decompositions:

11 + 537169 = 537180
23 + 537157 = 537180
37 + 537143 = 537180
47 + 537133 = 537180
53 + 537127 = 537180
89 + 537091 = 537180
101 + 537079 = 537180
109 + 537071 = 537180

Showing the first eight; more decompositions exist.
