Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103778, here are decompositions:

79 + 103699 = 103778
97 + 103681 = 103778
109 + 103669 = 103778
127 + 103651 = 103778
211 + 103567 = 103778
229 + 103549 = 103778
307 + 103471 = 103778
379 + 103399 = 103778

Showing the first eight; more decompositions exist.
