Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30500, here are decompositions:

3 + 30497 = 30500
7 + 30493 = 30500
31 + 30469 = 30500
73 + 30427 = 30500
97 + 30403 = 30500
109 + 30391 = 30500
181 + 30319 = 30500
193 + 30307 = 30500

Showing the first eight; more decompositions exist.
