Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140648, here are decompositions:

19 + 140629 = 140648
31 + 140617 = 140648
37 + 140611 = 140648
61 + 140587 = 140648
97 + 140551 = 140648
127 + 140521 = 140648
199 + 140449 = 140648
229 + 140419 = 140648

Showing the first eight; more decompositions exist.
