Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491652, here are decompositions:

13 + 491639 = 491652
19 + 491633 = 491652
41 + 491611 = 491652
59 + 491593 = 491652
61 + 491591 = 491652
71 + 491581 = 491652
113 + 491539 = 491652
149 + 491503 = 491652

Showing the first eight; more decompositions exist.
