Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2990, here are decompositions:

19 + 2971 = 2990
37 + 2953 = 2990
73 + 2917 = 2990
103 + 2887 = 2990
139 + 2851 = 2990
157 + 2833 = 2990
193 + 2797 = 2990
199 + 2791 = 2990

Showing the first eight; more decompositions exist.
