Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468770, here are decompositions:

13 + 31468757 = 31468770
43 + 31468727 = 31468770
71 + 31468699 = 31468770
103 + 31468667 = 31468770
139 + 31468631 = 31468770
173 + 31468597 = 31468770
181 + 31468589 = 31468770
197 + 31468573 = 31468770

Showing the first eight; more decompositions exist.
