Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19670, here are decompositions:

61 + 19609 = 19670
67 + 19603 = 19670
73 + 19597 = 19670
127 + 19543 = 19670
139 + 19531 = 19670
163 + 19507 = 19670
181 + 19489 = 19670
193 + 19477 = 19670

Showing the first eight; more decompositions exist.
