Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541514, here are decompositions:

5 + 31541509 = 31541514
7 + 31541507 = 31541514
31 + 31541483 = 31541514
47 + 31541467 = 31541514
97 + 31541417 = 31541514
113 + 31541401 = 31541514
167 + 31541347 = 31541514
233 + 31541281 = 31541514

Showing the first eight; more decompositions exist.
