Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30558, here are decompositions:

5 + 30553 = 30558
19 + 30539 = 30558
29 + 30529 = 30558
41 + 30517 = 30558
61 + 30497 = 30558
67 + 30491 = 30558
89 + 30469 = 30558
109 + 30449 = 30558

Showing the first eight; more decompositions exist.
