Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466742, here are decompositions:

11 + 31466731 = 31466742
23 + 31466719 = 31466742
29 + 31466713 = 31466742
53 + 31466689 = 31466742
71 + 31466671 = 31466742
113 + 31466629 = 31466742
179 + 31466563 = 31466742
193 + 31466549 = 31466742

Showing the first eight; more decompositions exist.
