Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454852, here are decompositions:

43 + 31454809 = 31454852
151 + 31454701 = 31454852
199 + 31454653 = 31454852
421 + 31454431 = 31454852
463 + 31454389 = 31454852
631 + 31454221 = 31454852
661 + 31454191 = 31454852
691 + 31454161 = 31454852

Showing the first eight; more decompositions exist.
