Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542024, here are decompositions:

11 + 31542013 = 31542024
13 + 31542011 = 31542024
23 + 31542001 = 31542024
43 + 31541981 = 31542024
47 + 31541977 = 31542024
53 + 31541971 = 31542024
131 + 31541893 = 31542024
167 + 31541857 = 31542024

Showing the first eight; more decompositions exist.
