Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469166, here are decompositions:

23 + 31469143 = 31469166
97 + 31469069 = 31469166
139 + 31469027 = 31469166
173 + 31468993 = 31469166
199 + 31468967 = 31469166
263 + 31468903 = 31469166
317 + 31468849 = 31469166
373 + 31468793 = 31469166

Showing the first eight; more decompositions exist.
