Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513972, here are decompositions:

29 + 513943 = 513972
73 + 513899 = 513972
101 + 513871 = 513972
131 + 513841 = 513972
191 + 513781 = 513972
211 + 513761 = 513972
223 + 513749 = 513972
233 + 513739 = 513972

Showing the first eight; more decompositions exist.
