Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527978, here are decompositions:

37 + 527941 = 527978
97 + 527881 = 527978
109 + 527869 = 527978
127 + 527851 = 527978
229 + 527749 = 527978
277 + 527701 = 527978
307 + 527671 = 527978
379 + 527599 = 527978

Showing the first eight; more decompositions exist.
