Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38018, here are decompositions:

7 + 38011 = 38018
31 + 37987 = 38018
61 + 37957 = 38018
67 + 37951 = 38018
139 + 37879 = 38018
157 + 37861 = 38018
271 + 37747 = 38018
439 + 37579 = 38018

Showing the first eight; more decompositions exist.
