Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29870, here are decompositions:

3 + 29867 = 29870
7 + 29863 = 29870
19 + 29851 = 29870
37 + 29833 = 29870
67 + 29803 = 29870
109 + 29761 = 29870
199 + 29671 = 29870
229 + 29641 = 29870

Showing the first eight; more decompositions exist.
