Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515498, here are decompositions:

97 + 515401 = 515498
127 + 515371 = 515498
271 + 515227 = 515498
307 + 515191 = 515498
349 + 515149 = 515498
409 + 515089 = 515498
457 + 515041 = 515498
631 + 514867 = 515498

Showing the first eight; more decompositions exist.
