Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38442, here are decompositions:

11 + 38431 = 38442
71 + 38371 = 38442
109 + 38333 = 38442
113 + 38329 = 38442
139 + 38303 = 38442
181 + 38261 = 38442
211 + 38231 = 38442
223 + 38219 = 38442

Showing the first eight; more decompositions exist.
