Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001908, here are decompositions:

101 + 1001807 = 1001908
107 + 1001801 = 1001908
239 + 1001669 = 1001908
269 + 1001639 = 1001908
359 + 1001549 = 1001908
449 + 1001459 = 1001908
461 + 1001447 = 1001908
521 + 1001387 = 1001908

Showing the first eight; more decompositions exist.
