Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38144, here are decompositions:

31 + 38113 = 38144
61 + 38083 = 38144
97 + 38047 = 38144
151 + 37993 = 38144
157 + 37987 = 38144
181 + 37963 = 38144
193 + 37951 = 38144
283 + 37861 = 38144

Showing the first eight; more decompositions exist.
