Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454604, here are decompositions:

17 + 31454587 = 31454604
107 + 31454497 = 31454604
163 + 31454441 = 31454604
173 + 31454431 = 31454604
227 + 31454377 = 31454604
283 + 31454321 = 31454604
383 + 31454221 = 31454604
443 + 31454161 = 31454604

Showing the first eight; more decompositions exist.
