Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27938, here are decompositions:

19 + 27919 = 27938
37 + 27901 = 27938
139 + 27799 = 27938
199 + 27739 = 27938
241 + 27697 = 27938
307 + 27631 = 27938
397 + 27541 = 27938
409 + 27529 = 27938

Showing the first eight; more decompositions exist.
