Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468100, here are decompositions:

3 + 31468097 = 31468100
73 + 31468027 = 31468100
151 + 31467949 = 31468100
163 + 31467937 = 31468100
271 + 31467829 = 31468100
337 + 31467763 = 31468100
373 + 31467727 = 31468100
379 + 31467721 = 31468100

Showing the first eight; more decompositions exist.
