Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103426, here are decompositions:

3 + 103423 = 103426
5 + 103421 = 103426
17 + 103409 = 103426
107 + 103319 = 103426
137 + 103289 = 103426
347 + 103079 = 103426
359 + 103067 = 103426
383 + 103043 = 103426

Showing the first eight; more decompositions exist.
