Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468072, here are decompositions:

5 + 31468067 = 31468072
59 + 31468013 = 31468072
71 + 31468001 = 31468072
89 + 31467983 = 31468072
173 + 31467899 = 31468072
179 + 31467893 = 31468072
263 + 31467809 = 31468072
353 + 31467719 = 31468072

Showing the first eight; more decompositions exist.
