Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555952, here are decompositions:

3 + 31555949 = 31555952
13 + 31555939 = 31555952
19 + 31555933 = 31555952
31 + 31555921 = 31555952
61 + 31555891 = 31555952
79 + 31555873 = 31555952
139 + 31555813 = 31555952
349 + 31555603 = 31555952

Showing the first eight; more decompositions exist.
