Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38842, here are decompositions:

3 + 38839 = 38842
59 + 38783 = 38842
113 + 38729 = 38842
131 + 38711 = 38842
149 + 38693 = 38842
173 + 38669 = 38842
191 + 38651 = 38842
233 + 38609 = 38842

Showing the first eight; more decompositions exist.
