Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87938, here are decompositions:

7 + 87931 = 87938
61 + 87877 = 87938
127 + 87811 = 87938
199 + 87739 = 87938
241 + 87697 = 87938
307 + 87631 = 87938
349 + 87589 = 87938
379 + 87559 = 87938

Showing the first eight; more decompositions exist.
