Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143706, here are decompositions:

7 + 143699 = 143706
19 + 143687 = 143706
29 + 143677 = 143706
37 + 143669 = 143706
53 + 143653 = 143706
89 + 143617 = 143706
97 + 143609 = 143706
113 + 143593 = 143706

Showing the first eight; more decompositions exist.
