Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468318, here are decompositions:

29 + 31468289 = 31468318
47 + 31468271 = 31468318
59 + 31468259 = 31468318
71 + 31468247 = 31468318
107 + 31468211 = 31468318
149 + 31468169 = 31468318
251 + 31468067 = 31468318
317 + 31468001 = 31468318

Showing the first eight; more decompositions exist.
