Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22430, here are decompositions:

61 + 22369 = 22430
127 + 22303 = 22430
139 + 22291 = 22430
151 + 22279 = 22430
157 + 22273 = 22430
241 + 22189 = 22430
271 + 22159 = 22430
277 + 22153 = 22430

Showing the first eight; more decompositions exist.
