Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7540, here are decompositions:

3 + 7537 = 7540
11 + 7529 = 7540
17 + 7523 = 7540
23 + 7517 = 7540
41 + 7499 = 7540
53 + 7487 = 7540
59 + 7481 = 7540
83 + 7457 = 7540

Showing the first eight; more decompositions exist.
