Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627480, here are decompositions:

89 + 31627391 = 31627480
107 + 31627373 = 31627480
191 + 31627289 = 31627480
233 + 31627247 = 31627480
263 + 31627217 = 31627480
347 + 31627133 = 31627480
359 + 31627121 = 31627480
389 + 31627091 = 31627480

Showing the first eight; more decompositions exist.
