Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511684, here are decompositions:

53 + 511631 = 511684
101 + 511583 = 511684
197 + 511487 = 511684
227 + 511457 = 511684
293 + 511391 = 511684
347 + 511337 = 511684
461 + 511223 = 511684
491 + 511193 = 511684

Showing the first eight; more decompositions exist.
