Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454684, here are decompositions:

3 + 31454681 = 31454684
31 + 31454653 = 31454684
97 + 31454587 = 31454684
223 + 31454461 = 31454684
307 + 31454377 = 31454684
421 + 31454263 = 31454684
463 + 31454221 = 31454684
487 + 31454197 = 31454684

Showing the first eight; more decompositions exist.
