Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468508, here are decompositions:

37 + 31468471 = 31468508
61 + 31468447 = 31468508
109 + 31468399 = 31468508
139 + 31468369 = 31468508
277 + 31468231 = 31468508
307 + 31468201 = 31468508
349 + 31468159 = 31468508
541 + 31467967 = 31468508

Showing the first eight; more decompositions exist.
