Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7568, here are decompositions:

7 + 7561 = 7568
19 + 7549 = 7568
31 + 7537 = 7568
61 + 7507 = 7568
79 + 7489 = 7568
109 + 7459 = 7568
151 + 7417 = 7568
157 + 7411 = 7568

Showing the first eight; more decompositions exist.
