Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001642, here are decompositions:

3 + 1001639 = 1001642
13 + 1001629 = 1001642
73 + 1001569 = 1001642
79 + 1001563 = 1001642
151 + 1001491 = 1001642
211 + 1001431 = 1001642
241 + 1001401 = 1001642
331 + 1001311 = 1001642

Showing the first eight; more decompositions exist.
