Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65558, here are decompositions:

7 + 65551 = 65558
19 + 65539 = 65558
37 + 65521 = 65558
61 + 65497 = 65558
79 + 65479 = 65558
109 + 65449 = 65558
139 + 65419 = 65558
151 + 65407 = 65558

Showing the first eight; more decompositions exist.
