Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103558, here are decompositions:

5 + 103553 = 103558
29 + 103529 = 103558
47 + 103511 = 103558
101 + 103457 = 103558
107 + 103451 = 103558
137 + 103421 = 103558
149 + 103409 = 103558
167 + 103391 = 103558

Showing the first eight; more decompositions exist.
