Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971900, here are decompositions:

37 + 971863 = 971900
43 + 971857 = 971900
67 + 971833 = 971900
79 + 971821 = 971900
331 + 971569 = 971900
337 + 971563 = 971900
379 + 971521 = 971900
409 + 971491 = 971900

Showing the first eight; more decompositions exist.
