Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37838, here are decompositions:

7 + 37831 = 37838
139 + 37699 = 37838
181 + 37657 = 37838
271 + 37567 = 37838
277 + 37561 = 37838
331 + 37507 = 37838
337 + 37501 = 37838
349 + 37489 = 37838

Showing the first eight; more decompositions exist.
