Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527828, here are decompositions:

19 + 527809 = 527828
79 + 527749 = 527828
127 + 527701 = 527828
157 + 527671 = 527828
229 + 527599 = 527828
271 + 527557 = 527828
409 + 527419 = 527828
421 + 527407 = 527828

Showing the first eight; more decompositions exist.
