Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971810, here are decompositions:

43 + 971767 = 971810
97 + 971713 = 971810
127 + 971683 = 971810
157 + 971653 = 971810
241 + 971569 = 971810
331 + 971479 = 971810
337 + 971473 = 971810
409 + 971401 = 971810

Showing the first eight; more decompositions exist.
