Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552276, here are decompositions:

5 + 31552271 = 31552276
23 + 31552253 = 31552276
47 + 31552229 = 31552276
83 + 31552193 = 31552276
137 + 31552139 = 31552276
149 + 31552127 = 31552276
227 + 31552049 = 31552276
257 + 31552019 = 31552276

Showing the first eight; more decompositions exist.
