Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001878, here are decompositions:

47 + 1001831 = 1001878
71 + 1001807 = 1001878
191 + 1001687 = 1001878
239 + 1001639 = 1001878
257 + 1001621 = 1001878
347 + 1001531 = 1001878
419 + 1001459 = 1001878
431 + 1001447 = 1001878

Showing the first eight; more decompositions exist.
