Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468550, here are decompositions:

7 + 31468543 = 31468550
79 + 31468471 = 31468550
97 + 31468453 = 31468550
103 + 31468447 = 31468550
151 + 31468399 = 31468550
181 + 31468369 = 31468550
307 + 31468243 = 31468550
349 + 31468201 = 31468550

Showing the first eight; more decompositions exist.
