Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11420, here are decompositions:

37 + 11383 = 11420
67 + 11353 = 11420
103 + 11317 = 11420
109 + 11311 = 11420
163 + 11257 = 11420
181 + 11239 = 11420
223 + 11197 = 11420
271 + 11149 = 11420

Showing the first eight; more decompositions exist.
