Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105538, here are decompositions:

5 + 105533 = 105538
11 + 105527 = 105538
29 + 105509 = 105538
47 + 105491 = 105538
71 + 105467 = 105538
89 + 105449 = 105538
101 + 105437 = 105538
131 + 105407 = 105538

Showing the first eight; more decompositions exist.
