Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537988, here are decompositions:

47 + 537941 = 537988
89 + 537899 = 537988
239 + 537749 = 537988
389 + 537599 = 537988
401 + 537587 = 537988
419 + 537569 = 537988
461 + 537527 = 537988
491 + 537497 = 537988

Showing the first eight; more decompositions exist.
