Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468628, here are decompositions:

31 + 31468597 = 31468628
157 + 31468471 = 31468628
181 + 31468447 = 31468628
229 + 31468399 = 31468628
397 + 31468231 = 31468628
601 + 31468027 = 31468628
661 + 31467967 = 31468628
691 + 31467937 = 31468628

Showing the first eight; more decompositions exist.
