Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528812, here are decompositions:

13 + 528799 = 528812
103 + 528709 = 528812
139 + 528673 = 528812
181 + 528631 = 528812
379 + 528433 = 528812
409 + 528403 = 528812
421 + 528391 = 528812
439 + 528373 = 528812

Showing the first eight; more decompositions exist.
