Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971786, here are decompositions:

3 + 971783 = 971786
19 + 971767 = 971786
73 + 971713 = 971786
103 + 971683 = 971786
223 + 971563 = 971786
307 + 971479 = 971786
313 + 971473 = 971786
367 + 971419 = 971786

Showing the first eight; more decompositions exist.
