Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454600, here are decompositions:

13 + 31454587 = 31454600
103 + 31454497 = 31454600
139 + 31454461 = 31454600
211 + 31454389 = 31454600
223 + 31454377 = 31454600
337 + 31454263 = 31454600
379 + 31454221 = 31454600
409 + 31454191 = 31454600

Showing the first eight; more decompositions exist.
