Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525728, here are decompositions:

19 + 525709 = 525728
31 + 525697 = 525728
79 + 525649 = 525728
157 + 525571 = 525728
199 + 525529 = 525728
211 + 525517 = 525728
271 + 525457 = 525728
331 + 525397 = 525728

Showing the first eight; more decompositions exist.
