Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30752, here are decompositions:

103 + 30649 = 30752
109 + 30643 = 30752
193 + 30559 = 30752
199 + 30553 = 30752
223 + 30529 = 30752
283 + 30469 = 30752
349 + 30403 = 30752
433 + 30319 = 30752

Showing the first eight; more decompositions exist.
