Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552452, here are decompositions:

23 + 31552429 = 31552452
31 + 31552421 = 31552452
59 + 31552393 = 31552452
101 + 31552351 = 31552452
149 + 31552303 = 31552452
181 + 31552271 = 31552452
199 + 31552253 = 31552452
223 + 31552229 = 31552452

Showing the first eight; more decompositions exist.
