Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139698, here are decompositions:

17 + 139681 = 139698
37 + 139661 = 139698
71 + 139627 = 139698
79 + 139619 = 139698
89 + 139609 = 139698
101 + 139597 = 139698
107 + 139591 = 139698
109 + 139589 = 139698

Showing the first eight; more decompositions exist.
