Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104438, here are decompositions:

127 + 104311 = 104438
151 + 104287 = 104438
157 + 104281 = 104438
199 + 104239 = 104438
277 + 104161 = 104438
331 + 104107 = 104438
349 + 104089 = 104438
379 + 104059 = 104438

Showing the first eight; more decompositions exist.
