Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931838, here are decompositions:

109 + 931729 = 931838
181 + 931657 = 931838
199 + 931639 = 931838
241 + 931597 = 931838
421 + 931417 = 931838
487 + 931351 = 931838
571 + 931267 = 931838
601 + 931237 = 931838

Showing the first eight; more decompositions exist.
