Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2906, here are decompositions:

3 + 2903 = 2906
19 + 2887 = 2906
73 + 2833 = 2906
103 + 2803 = 2906
109 + 2797 = 2906
139 + 2767 = 2906
157 + 2749 = 2906
193 + 2713 = 2906

Showing the first eight; more decompositions exist.
