Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528188, here are decompositions:

61 + 528127 = 528188
97 + 528091 = 528188
307 + 527881 = 528188
337 + 527851 = 528188
379 + 527809 = 528188
439 + 527749 = 528188
487 + 527701 = 528188
607 + 527581 = 528188

Showing the first eight; more decompositions exist.
