Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461354, here are decompositions:

5 + 31461349 = 31461354
11 + 31461343 = 31461354
13 + 31461341 = 31461354
53 + 31461301 = 31461354
61 + 31461293 = 31461354
73 + 31461281 = 31461354
101 + 31461253 = 31461354
131 + 31461223 = 31461354

Showing the first eight; more decompositions exist.
