Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7556, here are decompositions:

7 + 7549 = 7556
19 + 7537 = 7556
67 + 7489 = 7556
79 + 7477 = 7556
97 + 7459 = 7556
139 + 7417 = 7556
163 + 7393 = 7556
223 + 7333 = 7556

Showing the first eight; more decompositions exist.
