Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541574, here are decompositions:

5 + 31541569 = 31541574
11 + 31541563 = 31541574
17 + 31541557 = 31541574
47 + 31541527 = 31541574
67 + 31541507 = 31541574
107 + 31541467 = 31541574
137 + 31541437 = 31541574
157 + 31541417 = 31541574

Showing the first eight; more decompositions exist.
