Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468204, here are decompositions:

3 + 31468201 = 31468204
107 + 31468097 = 31468204
137 + 31468067 = 31468204
191 + 31468013 = 31468204
293 + 31467911 = 31468204
311 + 31467893 = 31468204
557 + 31467647 = 31468204
617 + 31467587 = 31468204

Showing the first eight; more decompositions exist.
