Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39442, here are decompositions:

3 + 39439 = 39442
23 + 39419 = 39442
59 + 39383 = 39442
71 + 39371 = 39442
83 + 39359 = 39442
101 + 39341 = 39442
149 + 39293 = 39442
191 + 39251 = 39442

Showing the first eight; more decompositions exist.
