Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103784, here are decompositions:

61 + 103723 = 103784
97 + 103687 = 103784
103 + 103681 = 103784
127 + 103657 = 103784
193 + 103591 = 103784
211 + 103573 = 103784
223 + 103561 = 103784
313 + 103471 = 103784

Showing the first eight; more decompositions exist.
