Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515344, here are decompositions:

107 + 515237 = 515344
113 + 515231 = 515344
191 + 515153 = 515344
233 + 515111 = 515344
257 + 515087 = 515344
491 + 514853 = 515344
503 + 514841 = 515344
521 + 514823 = 515344

Showing the first eight; more decompositions exist.
