Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463418, here are decompositions:

11 + 31463407 = 31463418
29 + 31463389 = 31463418
31 + 31463387 = 31463418
89 + 31463329 = 31463418
97 + 31463321 = 31463418
101 + 31463317 = 31463418
137 + 31463281 = 31463418
149 + 31463269 = 31463418

Showing the first eight; more decompositions exist.
