Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528760, here are decompositions:

41 + 528719 = 528760
53 + 528707 = 528760
101 + 528659 = 528760
131 + 528629 = 528760
137 + 528623 = 528760
149 + 528611 = 528760
233 + 528527 = 528760
251 + 528509 = 528760

Showing the first eight; more decompositions exist.
