Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468762, here are decompositions:

5 + 31468757 = 31468762
131 + 31468631 = 31468762
173 + 31468589 = 31468762
191 + 31468571 = 31468762
233 + 31468529 = 31468762
239 + 31468523 = 31468762
251 + 31468511 = 31468762
263 + 31468499 = 31468762

Showing the first eight; more decompositions exist.
