Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001618, here are decompositions:

31 + 1001587 = 1001618
67 + 1001551 = 1001618
127 + 1001491 = 1001618
151 + 1001467 = 1001618
229 + 1001389 = 1001618
271 + 1001347 = 1001618
307 + 1001311 = 1001618
421 + 1001197 = 1001618

Showing the first eight; more decompositions exist.
