Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454882, here are decompositions:

73 + 31454809 = 31454882
181 + 31454701 = 31454882
229 + 31454653 = 31454882
421 + 31454461 = 31454882
499 + 31454383 = 31454882
619 + 31454263 = 31454882
661 + 31454221 = 31454882
691 + 31454191 = 31454882

Showing the first eight; more decompositions exist.
