Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527766, here are decompositions:

89 + 31527677 = 31527766
107 + 31527659 = 31527766
197 + 31527569 = 31527766
233 + 31527533 = 31527766
269 + 31527497 = 31527766
353 + 31527413 = 31527766
359 + 31527407 = 31527766
443 + 31527323 = 31527766

Showing the first eight; more decompositions exist.
