Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627336, here are decompositions:

3 + 31627333 = 31627336
17 + 31627319 = 31627336
47 + 31627289 = 31627336
89 + 31627247 = 31627336
263 + 31627073 = 31627336
359 + 31626977 = 31627336
443 + 31626893 = 31627336
467 + 31626869 = 31627336

Showing the first eight; more decompositions exist.
