Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28550, here are decompositions:

3 + 28547 = 28550
13 + 28537 = 28550
37 + 28513 = 28550
73 + 28477 = 28550
103 + 28447 = 28550
139 + 28411 = 28550
157 + 28393 = 28550
163 + 28387 = 28550

Showing the first eight; more decompositions exist.
