Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627296, here are decompositions:

7 + 31627289 = 31627296
47 + 31627249 = 31627296
53 + 31627243 = 31627296
59 + 31627237 = 31627296
79 + 31627217 = 31627296
163 + 31627133 = 31627296
223 + 31627073 = 31627296
227 + 31627069 = 31627296

Showing the first eight; more decompositions exist.
