Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22990, here are decompositions:

17 + 22973 = 22990
29 + 22961 = 22990
47 + 22943 = 22990
53 + 22937 = 22990
83 + 22907 = 22990
89 + 22901 = 22990
113 + 22877 = 22990
131 + 22859 = 22990

Showing the first eight; more decompositions exist.
