Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30486, here are decompositions:

17 + 30469 = 30486
19 + 30467 = 30486
37 + 30449 = 30486
59 + 30427 = 30486
83 + 30403 = 30486
97 + 30389 = 30486
139 + 30347 = 30486
163 + 30323 = 30486

Showing the first eight; more decompositions exist.
