Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528976, here are decompositions:

7 + 31528969 = 31528976
67 + 31528909 = 31528976
163 + 31528813 = 31528976
307 + 31528669 = 31528976
397 + 31528579 = 31528976
613 + 31528363 = 31528976
709 + 31528267 = 31528976
769 + 31528207 = 31528976

Showing the first eight; more decompositions exist.
