Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468032, here are decompositions:

5 + 31468027 = 31468032
19 + 31468013 = 31468032
31 + 31468001 = 31468032
83 + 31467949 = 31468032
139 + 31467893 = 31468032
179 + 31467853 = 31468032
223 + 31467809 = 31468032
269 + 31467763 = 31468032

Showing the first eight; more decompositions exist.
