Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515402, here are decompositions:

31 + 515371 = 515402
79 + 515323 = 515402
109 + 515293 = 515402
211 + 515191 = 515402
229 + 515173 = 515402
313 + 515089 = 515402
463 + 514939 = 515402
499 + 514903 = 515402

Showing the first eight; more decompositions exist.
