Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515294, here are decompositions:

61 + 515233 = 515294
67 + 515227 = 515294
103 + 515191 = 515294
151 + 515143 = 515294
421 + 514873 = 515294
463 + 514831 = 515294
547 + 514747 = 515294
613 + 514681 = 515294

Showing the first eight; more decompositions exist.
