Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469006, here are decompositions:

13 + 31468993 = 31469006
43 + 31468963 = 31469006
103 + 31468903 = 31469006
157 + 31468849 = 31469006
229 + 31468777 = 31469006
307 + 31468699 = 31469006
409 + 31468597 = 31469006
433 + 31468573 = 31469006

Showing the first eight; more decompositions exist.
