Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38390, here are decompositions:

13 + 38377 = 38390
19 + 38371 = 38390
61 + 38329 = 38390
73 + 38317 = 38390
103 + 38287 = 38390
109 + 38281 = 38390
151 + 38239 = 38390
193 + 38197 = 38390

Showing the first eight; more decompositions exist.
