Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139298, here are decompositions:

7 + 139291 = 139298
31 + 139267 = 139298
97 + 139201 = 139298
277 + 139021 = 139298
331 + 138967 = 139298
409 + 138889 = 139298
457 + 138841 = 139298
499 + 138799 = 139298

Showing the first eight; more decompositions exist.
