Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468308, here are decompositions:

19 + 31468289 = 31468308
37 + 31468271 = 31468308
61 + 31468247 = 31468308
97 + 31468211 = 31468308
107 + 31468201 = 31468308
139 + 31468169 = 31468308
149 + 31468159 = 31468308
211 + 31468097 = 31468308

Showing the first eight; more decompositions exist.
