Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528374, here are decompositions:

61 + 528313 = 528374
127 + 528247 = 528374
151 + 528223 = 528374
157 + 528217 = 528374
211 + 528163 = 528374
277 + 528097 = 528374
283 + 528091 = 528374
331 + 528043 = 528374

Showing the first eight; more decompositions exist.
