Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627754, here are decompositions:

3 + 31627751 = 31627754
127 + 31627627 = 31627754
181 + 31627573 = 31627754
211 + 31627543 = 31627754
271 + 31627483 = 31627754
397 + 31627357 = 31627754
421 + 31627333 = 31627754
727 + 31627027 = 31627754

Showing the first eight; more decompositions exist.
