Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516142, here are decompositions:

89 + 516053 = 516142
149 + 515993 = 516142
173 + 515969 = 516142
191 + 515951 = 516142
269 + 515873 = 516142
281 + 515861 = 516142
359 + 515783 = 516142
401 + 515741 = 516142

Showing the first eight; more decompositions exist.
