Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38154, here are decompositions:

5 + 38149 = 38154
41 + 38113 = 38154
71 + 38083 = 38154
101 + 38053 = 38154
107 + 38047 = 38154
157 + 37997 = 38154
163 + 37991 = 38154
167 + 37987 = 38154

Showing the first eight; more decompositions exist.
