Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38128, here are decompositions:

59 + 38069 = 38128
89 + 38039 = 38128
131 + 37997 = 38128
137 + 37991 = 38128
239 + 37889 = 38128
257 + 37871 = 38128
281 + 37847 = 38128
317 + 37811 = 38128

Showing the first eight; more decompositions exist.
