Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139976, here are decompositions:

7 + 139969 = 139976
37 + 139939 = 139976
139 + 139837 = 139976
163 + 139813 = 139976
223 + 139753 = 139976
229 + 139747 = 139976
313 + 139663 = 139976
349 + 139627 = 139976

Showing the first eight; more decompositions exist.
