Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7636, here are decompositions:

29 + 7607 = 7636
47 + 7589 = 7636
53 + 7583 = 7636
59 + 7577 = 7636
89 + 7547 = 7636
107 + 7529 = 7636
113 + 7523 = 7636
137 + 7499 = 7636

Showing the first eight; more decompositions exist.
