Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454814, here are decompositions:

5 + 31454809 = 31454814
31 + 31454783 = 31454814
73 + 31454741 = 31454814
113 + 31454701 = 31454814
163 + 31454651 = 31454814
227 + 31454587 = 31454814
317 + 31454497 = 31454814
331 + 31454483 = 31454814

Showing the first eight; more decompositions exist.
