Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627434, here are decompositions:

23 + 31627411 = 31627434
43 + 31627391 = 31627434
61 + 31627373 = 31627434
101 + 31627333 = 31627434
131 + 31627303 = 31627434
173 + 31627261 = 31627434
191 + 31627243 = 31627434
197 + 31627237 = 31627434

Showing the first eight; more decompositions exist.
