Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17558, here are decompositions:

7 + 17551 = 17558
19 + 17539 = 17558
61 + 17497 = 17558
67 + 17491 = 17558
109 + 17449 = 17558
127 + 17431 = 17558
139 + 17419 = 17558
157 + 17401 = 17558

Showing the first eight; more decompositions exist.
