Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527542, here are decompositions:

53 + 527489 = 527542
89 + 527453 = 527542
101 + 527441 = 527542
131 + 527411 = 527542
149 + 527393 = 527542
251 + 527291 = 527542
269 + 527273 = 527542
383 + 527159 = 527542

Showing the first eight; more decompositions exist.
