Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527778, here are decompositions:

29 + 527749 = 527778
37 + 527741 = 527778
79 + 527699 = 527778
107 + 527671 = 527778
151 + 527627 = 527778
179 + 527599 = 527778
197 + 527581 = 527778
271 + 527507 = 527778

Showing the first eight; more decompositions exist.
