Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103828, here are decompositions:

17 + 103811 = 103828
41 + 103787 = 103828
59 + 103769 = 103828
251 + 103577 = 103828
317 + 103511 = 103828
419 + 103409 = 103828
479 + 103349 = 103828
509 + 103319 = 103828

Showing the first eight; more decompositions exist.
