Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38142, here are decompositions:

23 + 38119 = 38142
29 + 38113 = 38142
59 + 38083 = 38142
73 + 38069 = 38142
89 + 38053 = 38142
103 + 38039 = 38142
131 + 38011 = 38142
149 + 37993 = 38142

Showing the first eight; more decompositions exist.
