Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461552, here are decompositions:

19 + 31461533 = 31461552
29 + 31461523 = 31461552
71 + 31461481 = 31461552
139 + 31461413 = 31461552
149 + 31461403 = 31461552
191 + 31461361 = 31461552
211 + 31461341 = 31461552
251 + 31461301 = 31461552

Showing the first eight; more decompositions exist.
