Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627486, here are decompositions:

3 + 31627483 = 31627486
113 + 31627373 = 31627486
167 + 31627319 = 31627486
197 + 31627289 = 31627486
239 + 31627247 = 31627486
269 + 31627217 = 31627486
353 + 31627133 = 31627486
479 + 31627007 = 31627486

Showing the first eight; more decompositions exist.
