Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527438, here are decompositions:

19 + 527419 = 527438
31 + 527407 = 527438
61 + 527377 = 527438
157 + 527281 = 527438
229 + 527209 = 527438
277 + 527161 = 527438
367 + 527071 = 527438
487 + 526951 = 527438

Showing the first eight; more decompositions exist.
