Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454630, here are decompositions:

3 + 31454627 = 31454630
43 + 31454587 = 31454630
199 + 31454431 = 31454630
241 + 31454389 = 31454630
367 + 31454263 = 31454630
409 + 31454221 = 31454630
433 + 31454197 = 31454630
439 + 31454191 = 31454630

Showing the first eight; more decompositions exist.
