Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29900, here are decompositions:

19 + 29881 = 29900
37 + 29863 = 29900
67 + 29833 = 29900
97 + 29803 = 29900
139 + 29761 = 29900
229 + 29671 = 29900
271 + 29629 = 29900
313 + 29587 = 29900

Showing the first eight; more decompositions exist.
