Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103540, here are decompositions:

11 + 103529 = 103540
29 + 103511 = 103540
83 + 103457 = 103540
89 + 103451 = 103540
131 + 103409 = 103540
149 + 103391 = 103540
191 + 103349 = 103540
233 + 103307 = 103540

Showing the first eight; more decompositions exist.
