Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515564, here are decompositions:

163 + 515401 = 515564
193 + 515371 = 515564
241 + 515323 = 515564
271 + 515293 = 515564
331 + 515233 = 515564
337 + 515227 = 515564
373 + 515191 = 515564
421 + 515143 = 515564

Showing the first eight; more decompositions exist.
