Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103798, here are decompositions:

11 + 103787 = 103798
29 + 103769 = 103798
179 + 103619 = 103798
269 + 103529 = 103798
347 + 103451 = 103798
389 + 103409 = 103798
449 + 103349 = 103798
479 + 103319 = 103798

Showing the first eight; more decompositions exist.
