Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453502, here are decompositions:

19 + 31453483 = 31453502
109 + 31453393 = 31453502
181 + 31453321 = 31453502
331 + 31453171 = 31453502
463 + 31453039 = 31453502
601 + 31452901 = 31453502
643 + 31452859 = 31453502
673 + 31452829 = 31453502

Showing the first eight; more decompositions exist.
