Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515012, here are decompositions:

73 + 514939 = 515012
79 + 514933 = 515012
109 + 514903 = 515012
139 + 514873 = 515012
181 + 514831 = 515012
193 + 514819 = 515012
229 + 514783 = 515012
271 + 514741 = 515012

Showing the first eight; more decompositions exist.
