Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528146, here are decompositions:

19 + 528127 = 528146
103 + 528043 = 528146
163 + 527983 = 528146
277 + 527869 = 528146
337 + 527809 = 528146
397 + 527749 = 528146
523 + 527623 = 528146
547 + 527599 = 528146

Showing the first eight; more decompositions exist.
