Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511748, here are decompositions:

37 + 511711 = 511748
79 + 511669 = 511748
157 + 511591 = 511748
199 + 511549 = 511748
229 + 511519 = 511748
241 + 511507 = 511748
271 + 511477 = 511748
331 + 511417 = 511748

Showing the first eight; more decompositions exist.
