Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552444, here are decompositions:

23 + 31552421 = 31552444
41 + 31552403 = 31552444
173 + 31552271 = 31552444
191 + 31552253 = 31552444
233 + 31552211 = 31552444
251 + 31552193 = 31552444
317 + 31552127 = 31552444
467 + 31551977 = 31552444

Showing the first eight; more decompositions exist.
