Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537440, here are decompositions:

37 + 537403 = 537440
61 + 537379 = 537440
67 + 537373 = 537440
97 + 537343 = 537440
109 + 537331 = 537440
199 + 537241 = 537440
271 + 537169 = 537440
283 + 537157 = 537440

Showing the first eight; more decompositions exist.
