Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143670, here are decompositions:

17 + 143653 = 143670
19 + 143651 = 143670
41 + 143629 = 143670
53 + 143617 = 143670
61 + 143609 = 143670
97 + 143573 = 143670
101 + 143569 = 143670
103 + 143567 = 143670

Showing the first eight; more decompositions exist.
