Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542326, here are decompositions:

3 + 31542323 = 31542326
97 + 31542229 = 31542326
163 + 31542163 = 31542326
223 + 31542103 = 31542326
313 + 31542013 = 31542326
337 + 31541989 = 31542326
349 + 31541977 = 31542326
433 + 31541893 = 31542326

Showing the first eight; more decompositions exist.
