Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512240, here are decompositions:

73 + 512167 = 512240
103 + 512137 = 512240
139 + 512101 = 512240
181 + 512059 = 512240
193 + 512047 = 512240
229 + 512011 = 512240
277 + 511963 = 512240
307 + 511933 = 512240

Showing the first eight; more decompositions exist.
