Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75540, here are decompositions:

7 + 75533 = 75540
13 + 75527 = 75540
19 + 75521 = 75540
29 + 75511 = 75540
37 + 75503 = 75540
61 + 75479 = 75540
103 + 75437 = 75540
109 + 75431 = 75540

Showing the first eight; more decompositions exist.
