Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009894, here are decompositions:

107 + 1009787 = 1009894
113 + 1009781 = 1009894
167 + 1009727 = 1009894
251 + 1009643 = 1009894
257 + 1009637 = 1009894
293 + 1009601 = 1009894
461 + 1009433 = 1009894
521 + 1009373 = 1009894

Showing the first eight; more decompositions exist.
