Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541710, here are decompositions:

3 + 31541707 = 31541710
17 + 31541693 = 31541710
59 + 31541651 = 31541710
113 + 31541597 = 31541710
227 + 31541483 = 31541710
281 + 31541429 = 31541710
293 + 31541417 = 31541710
311 + 31541399 = 31541710

Showing the first eight; more decompositions exist.
