Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515462, here are decompositions:

61 + 515401 = 515462
139 + 515323 = 515462
151 + 515311 = 515462
229 + 515233 = 515462
271 + 515191 = 515462
313 + 515149 = 515462
373 + 515089 = 515462
421 + 515041 = 515462

Showing the first eight; more decompositions exist.
