Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527838, here are decompositions:

19 + 527819 = 527838
29 + 527809 = 527838
89 + 527749 = 527838
97 + 527741 = 527838
109 + 527729 = 527838
137 + 527701 = 527838
139 + 527699 = 527838
167 + 527671 = 527838

Showing the first eight; more decompositions exist.
