Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627598, here are decompositions:

31 + 31627567 = 31627598
61 + 31627537 = 31627598
97 + 31627501 = 31627598
241 + 31627357 = 31627598
337 + 31627261 = 31627598
349 + 31627249 = 31627598
397 + 31627201 = 31627598
547 + 31627051 = 31627598

Showing the first eight; more decompositions exist.
