Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469106, here are decompositions:

5 + 31469101 = 31469106
37 + 31469069 = 31469106
73 + 31469033 = 31469106
79 + 31469027 = 31469106
113 + 31468993 = 31469106
139 + 31468967 = 31469106
257 + 31468849 = 31469106
283 + 31468823 = 31469106

Showing the first eight; more decompositions exist.
