Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140186, here are decompositions:

19 + 140167 = 140186
43 + 140143 = 140186
199 + 139987 = 140186
349 + 139837 = 140186
373 + 139813 = 140186
433 + 139753 = 140186
439 + 139747 = 140186
457 + 139729 = 140186

Showing the first eight; more decompositions exist.
