Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31874, here are decompositions:

103 + 31771 = 31874
151 + 31723 = 31874
211 + 31663 = 31874
307 + 31567 = 31874
331 + 31543 = 31874
397 + 31477 = 31874
487 + 31387 = 31874
541 + 31333 = 31874

Showing the first eight; more decompositions exist.
