Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38642, here are decompositions:

3 + 38639 = 38642
13 + 38629 = 38642
31 + 38611 = 38642
73 + 38569 = 38642
181 + 38461 = 38642
193 + 38449 = 38642
211 + 38431 = 38642
271 + 38371 = 38642

Showing the first eight; more decompositions exist.
