Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627120, here are decompositions:

29 + 31627091 = 31627120
47 + 31627073 = 31627120
113 + 31627007 = 31627120
227 + 31626893 = 31627120
251 + 31626869 = 31627120
263 + 31626857 = 31627120
281 + 31626839 = 31627120
293 + 31626827 = 31627120

Showing the first eight; more decompositions exist.
