Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627392, here are decompositions:

19 + 31627373 = 31627392
59 + 31627333 = 31627392
73 + 31627319 = 31627392
89 + 31627303 = 31627392
103 + 31627289 = 31627392
131 + 31627261 = 31627392
149 + 31627243 = 31627392
191 + 31627201 = 31627392

Showing the first eight; more decompositions exist.
