Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527440, here are decompositions:

29 + 527411 = 527440
41 + 527399 = 527440
47 + 527393 = 527440
59 + 527381 = 527440
107 + 527333 = 527440
113 + 527327 = 527440
149 + 527291 = 527440
167 + 527273 = 527440

Showing the first eight; more decompositions exist.
