Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627292, here are decompositions:

3 + 31627289 = 31627292
31 + 31627261 = 31627292
43 + 31627249 = 31627292
223 + 31627069 = 31627292
241 + 31627051 = 31627292
313 + 31626979 = 31627292
349 + 31626943 = 31627292
409 + 31626883 = 31627292

Showing the first eight; more decompositions exist.
