Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550582, here are decompositions:

13 + 31550569 = 31550582
43 + 31550539 = 31550582
73 + 31550509 = 31550582
103 + 31550479 = 31550582
181 + 31550401 = 31550582
211 + 31550371 = 31550582
229 + 31550353 = 31550582
331 + 31550251 = 31550582

Showing the first eight; more decompositions exist.
