Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555934, here are decompositions:

13 + 31555921 = 31555934
43 + 31555891 = 31555934
61 + 31555873 = 31555934
271 + 31555663 = 31555934
283 + 31555651 = 31555934
331 + 31555603 = 31555934
547 + 31555387 = 31555934
607 + 31555327 = 31555934

Showing the first eight; more decompositions exist.
