Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626982, here are decompositions:

3 + 31626979 = 31626982
5 + 31626977 = 31626982
83 + 31626899 = 31626982
89 + 31626893 = 31626982
113 + 31626869 = 31626982
293 + 31626689 = 31626982
419 + 31626563 = 31626982
449 + 31626533 = 31626982

Showing the first eight; more decompositions exist.
