Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527538, here are decompositions:

5 + 527533 = 527538
31 + 527507 = 527538
97 + 527441 = 527538
127 + 527411 = 527538
131 + 527407 = 527538
139 + 527399 = 527538
157 + 527381 = 527538
191 + 527347 = 527538

Showing the first eight; more decompositions exist.
