Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468702, here are decompositions:

3 + 31468699 = 31468702
71 + 31468631 = 31468702
113 + 31468589 = 31468702
131 + 31468571 = 31468702
149 + 31468553 = 31468702
173 + 31468529 = 31468702
179 + 31468523 = 31468702
191 + 31468511 = 31468702

Showing the first eight; more decompositions exist.
