Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527578, here are decompositions:

71 + 527507 = 527578
89 + 527489 = 527578
131 + 527447 = 527578
137 + 527441 = 527578
167 + 527411 = 527578
179 + 527399 = 527578
197 + 527381 = 527578
251 + 527327 = 527578

Showing the first eight; more decompositions exist.
