Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468520, here are decompositions:

3 + 31468517 = 31468520
67 + 31468453 = 31468520
73 + 31468447 = 31468520
151 + 31468369 = 31468520
277 + 31468243 = 31468520
373 + 31468147 = 31468520
571 + 31467949 = 31468520
673 + 31467847 = 31468520

Showing the first eight; more decompositions exist.
