Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541608, here are decompositions:

11 + 31541597 = 31541608
17 + 31541591 = 31541608
101 + 31541507 = 31541608
179 + 31541429 = 31541608
191 + 31541417 = 31541608
311 + 31541297 = 31541608
467 + 31541141 = 31541608
479 + 31541129 = 31541608

Showing the first eight; more decompositions exist.
