Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104390, here are decompositions:

7 + 104383 = 104390
43 + 104347 = 104390
67 + 104323 = 104390
79 + 104311 = 104390
103 + 104287 = 104390
109 + 104281 = 104390
151 + 104239 = 104390
157 + 104233 = 104390

Showing the first eight; more decompositions exist.
