Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32990, here are decompositions:

3 + 32987 = 32990
7 + 32983 = 32990
19 + 32971 = 32990
73 + 32917 = 32990
79 + 32911 = 32990
103 + 32887 = 32990
151 + 32839 = 32990
157 + 32833 = 32990

Showing the first eight; more decompositions exist.
