Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468030, here are decompositions:

3 + 31468027 = 31468030
17 + 31468013 = 31468030
29 + 31468001 = 31468030
47 + 31467983 = 31468030
131 + 31467899 = 31468030
137 + 31467893 = 31468030
263 + 31467767 = 31468030
311 + 31467719 = 31468030

Showing the first eight; more decompositions exist.
