Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537664, here are decompositions:

3 + 537661 = 537664
53 + 537611 = 537664
137 + 537527 = 537664
167 + 537497 = 537664
251 + 537413 = 537664
263 + 537401 = 537664
317 + 537347 = 537664
383 + 537281 = 537664

Showing the first eight; more decompositions exist.
