Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143712, here are decompositions:

13 + 143699 = 143712
43 + 143669 = 143712
59 + 143653 = 143712
61 + 143651 = 143712
83 + 143629 = 143712
103 + 143609 = 143712
139 + 143573 = 143712
193 + 143519 = 143712

Showing the first eight; more decompositions exist.
