Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103928, here are decompositions:

61 + 103867 = 103928
127 + 103801 = 103928
229 + 103699 = 103928
241 + 103687 = 103928
271 + 103657 = 103928
277 + 103651 = 103928
337 + 103591 = 103928
367 + 103561 = 103928

Showing the first eight; more decompositions exist.
