Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468538, here are decompositions:

67 + 31468471 = 31468538
139 + 31468399 = 31468538
307 + 31468231 = 31468538
337 + 31468201 = 31468538
379 + 31468159 = 31468538
571 + 31467967 = 31468538
601 + 31467937 = 31468538
691 + 31467847 = 31468538

Showing the first eight; more decompositions exist.
