Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464668, here are decompositions:

19 + 31464649 = 31464668
97 + 31464571 = 31464668
229 + 31464439 = 31464668
241 + 31464427 = 31464668
271 + 31464397 = 31464668
397 + 31464271 = 31464668
601 + 31464067 = 31464668
607 + 31464061 = 31464668

Showing the first eight; more decompositions exist.
