Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555296, here are decompositions:

7 + 31555289 = 31555296
29 + 31555267 = 31555296
37 + 31555259 = 31555296
43 + 31555253 = 31555296
53 + 31555243 = 31555296
67 + 31555229 = 31555296
109 + 31555187 = 31555296
139 + 31555157 = 31555296

Showing the first eight; more decompositions exist.
