Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469158, here are decompositions:

89 + 31469069 = 31469158
131 + 31469027 = 31469158
191 + 31468967 = 31469158
239 + 31468919 = 31469158
257 + 31468901 = 31469158
401 + 31468757 = 31469158
431 + 31468727 = 31469158
491 + 31468667 = 31469158

Showing the first eight; more decompositions exist.
