Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550676, here are decompositions:

5 + 31550671 = 31550676
83 + 31550593 = 31550676
89 + 31550587 = 31550676
103 + 31550573 = 31550676
107 + 31550569 = 31550676
137 + 31550539 = 31550676
139 + 31550537 = 31550676
167 + 31550509 = 31550676

Showing the first eight; more decompositions exist.
