Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492758, here are decompositions:

7 + 31492751 = 31492758
61 + 31492697 = 31492758
67 + 31492691 = 31492758
107 + 31492651 = 31492758
131 + 31492627 = 31492758
181 + 31492577 = 31492758
191 + 31492567 = 31492758
229 + 31492529 = 31492758

Showing the first eight; more decompositions exist.
