Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454594, here are decompositions:

7 + 31454587 = 31454594
97 + 31454497 = 31454594
163 + 31454431 = 31454594
211 + 31454383 = 31454594
331 + 31454263 = 31454594
373 + 31454221 = 31454594
397 + 31454197 = 31454594
433 + 31454161 = 31454594

Showing the first eight; more decompositions exist.
