Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4550, here are decompositions:

3 + 4547 = 4550
31 + 4519 = 4550
37 + 4513 = 4550
43 + 4507 = 4550
67 + 4483 = 4550
103 + 4447 = 4550
109 + 4441 = 4550
127 + 4423 = 4550

Showing the first eight; more decompositions exist.
