Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29990, here are decompositions:

7 + 29983 = 29990
31 + 29959 = 29990
43 + 29947 = 29990
73 + 29917 = 29990
109 + 29881 = 29990
127 + 29863 = 29990
139 + 29851 = 29990
157 + 29833 = 29990

Showing the first eight; more decompositions exist.
