Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7566, here are decompositions:

5 + 7561 = 7566
7 + 7559 = 7566
17 + 7549 = 7566
19 + 7547 = 7566
29 + 7537 = 7566
37 + 7529 = 7566
43 + 7523 = 7566
59 + 7507 = 7566

Showing the first eight; more decompositions exist.
