Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527768, here are decompositions:

59 + 31527709 = 31527768
67 + 31527701 = 31527768
71 + 31527697 = 31527768
79 + 31527689 = 31527768
109 + 31527659 = 31527768
191 + 31527577 = 31527768
199 + 31527569 = 31527768
227 + 31527541 = 31527768

Showing the first eight; more decompositions exist.
