Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460858, here are decompositions:

7 + 31460851 = 31460858
19 + 31460839 = 31460858
67 + 31460791 = 31460858
157 + 31460701 = 31460858
181 + 31460677 = 31460858
211 + 31460647 = 31460858
277 + 31460581 = 31460858
307 + 31460551 = 31460858

Showing the first eight; more decompositions exist.
