Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555326, here are decompositions:

7 + 31555319 = 31555326
13 + 31555313 = 31555326
29 + 31555297 = 31555326
37 + 31555289 = 31555326
59 + 31555267 = 31555326
67 + 31555259 = 31555326
73 + 31555253 = 31555326
83 + 31555243 = 31555326

Showing the first eight; more decompositions exist.
