Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515288, here are decompositions:

61 + 515227 = 515288
97 + 515191 = 515288
139 + 515149 = 515288
199 + 515089 = 515288
349 + 514939 = 515288
421 + 514867 = 515288
457 + 514831 = 515288
541 + 514747 = 515288

Showing the first eight; more decompositions exist.
