Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22442, here are decompositions:

61 + 22381 = 22442
73 + 22369 = 22442
139 + 22303 = 22442
151 + 22291 = 22442
163 + 22279 = 22442
271 + 22171 = 22442
283 + 22159 = 22442
313 + 22129 = 22442

Showing the first eight; more decompositions exist.
