Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7550, here are decompositions:

3 + 7547 = 7550
13 + 7537 = 7550
43 + 7507 = 7550
61 + 7489 = 7550
73 + 7477 = 7550
139 + 7411 = 7550
157 + 7393 = 7550
181 + 7369 = 7550

Showing the first eight; more decompositions exist.
