Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527530, here are decompositions:

23 + 527507 = 527530
41 + 527489 = 527530
83 + 527447 = 527530
89 + 527441 = 527530
131 + 527399 = 527530
137 + 527393 = 527530
149 + 527381 = 527530
197 + 527333 = 527530

Showing the first eight; more decompositions exist.
