Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528778, here are decompositions:

59 + 528719 = 528778
71 + 528707 = 528778
149 + 528629 = 528778
167 + 528611 = 528778
251 + 528527 = 528778
269 + 528509 = 528778
359 + 528419 = 528778
449 + 528329 = 528778

Showing the first eight; more decompositions exist.
