Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139828, here are decompositions:

41 + 139787 = 139828
89 + 139739 = 139828
107 + 139721 = 139828
131 + 139697 = 139828
167 + 139661 = 139828
239 + 139589 = 139828
257 + 139571 = 139828
281 + 139547 = 139828

Showing the first eight; more decompositions exist.
