Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542344, here are decompositions:

3 + 31542341 = 31542344
181 + 31542163 = 31542344
241 + 31542103 = 31542344
277 + 31542067 = 31542344
307 + 31542037 = 31542344
313 + 31542031 = 31542344
331 + 31542013 = 31542344
367 + 31541977 = 31542344

Showing the first eight; more decompositions exist.
