Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40712, here are decompositions:

3 + 40709 = 40712
13 + 40699 = 40712
19 + 40693 = 40712
73 + 40639 = 40712
103 + 40609 = 40712
181 + 40531 = 40712
193 + 40519 = 40712
229 + 40483 = 40712

Showing the first eight; more decompositions exist.
