Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546378, here are decompositions:

29 + 31546349 = 31546378
41 + 31546337 = 31546378
179 + 31546199 = 31546378
191 + 31546187 = 31546378
197 + 31546181 = 31546378
359 + 31546019 = 31546378
419 + 31545959 = 31546378
491 + 31545887 = 31546378

Showing the first eight; more decompositions exist.
