Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468260, here are decompositions:

13 + 31468247 = 31468260
17 + 31468243 = 31468260
29 + 31468231 = 31468260
37 + 31468223 = 31468260
59 + 31468201 = 31468260
101 + 31468159 = 31468260
113 + 31468147 = 31468260
163 + 31468097 = 31468260

Showing the first eight; more decompositions exist.
