Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140402, here are decompositions:

139 + 140263 = 140402
181 + 140221 = 140402
211 + 140191 = 140402
331 + 140071 = 140402
349 + 140053 = 140402
421 + 139981 = 140402
433 + 139969 = 140402
463 + 139939 = 140402

Showing the first eight; more decompositions exist.
