Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515276, here are decompositions:

43 + 515233 = 515276
103 + 515173 = 515276
127 + 515149 = 515276
337 + 514939 = 515276
373 + 514903 = 515276
409 + 514867 = 515276
457 + 514819 = 515276
607 + 514669 = 515276

Showing the first eight; more decompositions exist.
