Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30560, here are decompositions:

3 + 30557 = 30560
7 + 30553 = 30560
31 + 30529 = 30560
43 + 30517 = 30560
67 + 30493 = 30560
157 + 30403 = 30560
193 + 30367 = 30560
241 + 30319 = 30560

Showing the first eight; more decompositions exist.
