Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627396, here are decompositions:

5 + 31627391 = 31627396
23 + 31627373 = 31627396
107 + 31627289 = 31627396
149 + 31627247 = 31627396
179 + 31627217 = 31627396
263 + 31627133 = 31627396
389 + 31627007 = 31627396
419 + 31626977 = 31627396

Showing the first eight; more decompositions exist.
