Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468254, here are decompositions:

7 + 31468247 = 31468254
11 + 31468243 = 31468254
23 + 31468231 = 31468254
31 + 31468223 = 31468254
43 + 31468211 = 31468254
53 + 31468201 = 31468254
107 + 31468147 = 31468254
157 + 31468097 = 31468254

Showing the first eight; more decompositions exist.
