Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626976, here are decompositions:

83 + 31626893 = 31626976
107 + 31626869 = 31626976
137 + 31626839 = 31626976
149 + 31626827 = 31626976
179 + 31626797 = 31626976
419 + 31626557 = 31626976
443 + 31626533 = 31626976
569 + 31626407 = 31626976

Showing the first eight; more decompositions exist.
