Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139076, here are decompositions:

43 + 139033 = 139076
109 + 138967 = 139076
139 + 138937 = 139076
193 + 138883 = 139076
277 + 138799 = 139076
283 + 138793 = 139076
313 + 138763 = 139076
337 + 138739 = 139076

Showing the first eight; more decompositions exist.
