Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468622, here are decompositions:

79 + 31468543 = 31468622
151 + 31468471 = 31468622
223 + 31468399 = 31468622
379 + 31468243 = 31468622
421 + 31468201 = 31468622
463 + 31468159 = 31468622
673 + 31467949 = 31468622
769 + 31467853 = 31468622

Showing the first eight; more decompositions exist.
