Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515282, here are decompositions:

3 + 515279 = 515282
109 + 515173 = 515282
139 + 515143 = 515282
193 + 515089 = 515282
241 + 515041 = 515282
349 + 514933 = 515282
379 + 514903 = 515282
409 + 514873 = 515282

Showing the first eight; more decompositions exist.
