Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139092, here are decompositions:

13 + 139079 = 139092
59 + 139033 = 139092
71 + 139021 = 139092
193 + 138899 = 139092
199 + 138893 = 139092
223 + 138869 = 139092
229 + 138863 = 139092
251 + 138841 = 139092

Showing the first eight; more decompositions exist.
