Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627406, here are decompositions:

73 + 31627333 = 31627406
103 + 31627303 = 31627406
157 + 31627249 = 31627406
163 + 31627243 = 31627406
337 + 31627069 = 31627406
373 + 31627033 = 31627406
379 + 31627027 = 31627406
439 + 31626967 = 31627406

Showing the first eight; more decompositions exist.
