Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103378, here are decompositions:

29 + 103349 = 103378
59 + 103319 = 103378
71 + 103307 = 103378
89 + 103289 = 103378
311 + 103067 = 103378
449 + 102929 = 103378
467 + 102911 = 103378
617 + 102761 = 103378

Showing the first eight; more decompositions exist.
