Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528748, here are decompositions:

29 + 528719 = 528748
41 + 528707 = 528748
89 + 528659 = 528748
137 + 528611 = 528748
239 + 528509 = 528748
257 + 528491 = 528748
347 + 528401 = 528748
419 + 528329 = 528748

Showing the first eight; more decompositions exist.
