Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528422, here are decompositions:

3 + 528419 = 528422
19 + 528403 = 528422
31 + 528391 = 528422
109 + 528313 = 528422
199 + 528223 = 528422
331 + 528091 = 528422
379 + 528043 = 528422
409 + 528013 = 528422

Showing the first eight; more decompositions exist.
