Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122890, here are decompositions:

3 + 122887 = 122890
23 + 122867 = 122890
29 + 122861 = 122890
41 + 122849 = 122890
71 + 122819 = 122890
101 + 122789 = 122890
113 + 122777 = 122890
137 + 122753 = 122890

Showing the first eight; more decompositions exist.
