Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109838, here are decompositions:

7 + 109831 = 109838
19 + 109819 = 109838
31 + 109807 = 109838
97 + 109741 = 109838
199 + 109639 = 109838
229 + 109609 = 109838
241 + 109597 = 109838
271 + 109567 = 109838

Showing the first eight; more decompositions exist.
