Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627442, here are decompositions:

31 + 31627411 = 31627442
109 + 31627333 = 31627442
139 + 31627303 = 31627442
181 + 31627261 = 31627442
193 + 31627249 = 31627442
199 + 31627243 = 31627442
241 + 31627201 = 31627442
373 + 31627069 = 31627442

Showing the first eight; more decompositions exist.
