Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7654, here are decompositions:

5 + 7649 = 7654
11 + 7643 = 7654
47 + 7607 = 7654
71 + 7583 = 7654
107 + 7547 = 7654
113 + 7541 = 7654
131 + 7523 = 7654
137 + 7517 = 7654

Showing the first eight; more decompositions exist.
