Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30662, here are decompositions:

13 + 30649 = 30662
19 + 30643 = 30662
31 + 30631 = 30662
103 + 30559 = 30662
109 + 30553 = 30662
193 + 30469 = 30662
271 + 30391 = 30662
349 + 30313 = 30662

Showing the first eight; more decompositions exist.
