Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537228, here are decompositions:

7 + 537221 = 537228
31 + 537197 = 537228
37 + 537191 = 537228
47 + 537181 = 537228
59 + 537169 = 537228
71 + 537157 = 537228
101 + 537127 = 537228
137 + 537091 = 537228

Showing the first eight; more decompositions exist.
