Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001626, here are decompositions:

5 + 1001621 = 1001626
167 + 1001459 = 1001626
179 + 1001447 = 1001626
239 + 1001387 = 1001626
257 + 1001369 = 1001626
347 + 1001279 = 1001626
359 + 1001267 = 1001626
389 + 1001237 = 1001626

Showing the first eight; more decompositions exist.
