Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468648, here are decompositions:

11 + 31468637 = 31468648
17 + 31468631 = 31468648
59 + 31468589 = 31468648
89 + 31468559 = 31468648
131 + 31468517 = 31468648
137 + 31468511 = 31468648
149 + 31468499 = 31468648
251 + 31468397 = 31468648

Showing the first eight; more decompositions exist.
