Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527840, here are decompositions:

31 + 527809 = 527840
37 + 527803 = 527840
139 + 527701 = 527840
241 + 527599 = 527840
277 + 527563 = 527840
283 + 527557 = 527840
307 + 527533 = 527840
421 + 527419 = 527840

Showing the first eight; more decompositions exist.
