Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71670, here are decompositions:

7 + 71663 = 71670
23 + 71647 = 71670
37 + 71633 = 71670
73 + 71597 = 71670
101 + 71569 = 71670
107 + 71563 = 71670
167 + 71503 = 71670
191 + 71479 = 71670

Showing the first eight; more decompositions exist.
