Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537218, here are decompositions:

37 + 537181 = 537218
61 + 537157 = 537218
127 + 537091 = 537218
139 + 537079 = 537218
151 + 537067 = 537218
181 + 537037 = 537218
211 + 537007 = 537218
229 + 536989 = 537218

Showing the first eight; more decompositions exist.
