Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469858, here are decompositions:

61 + 31469797 = 31469858
97 + 31469761 = 31469858
127 + 31469731 = 31469858
229 + 31469629 = 31469858
271 + 31469587 = 31469858
331 + 31469527 = 31469858
571 + 31469287 = 31469858
619 + 31469239 = 31469858

Showing the first eight; more decompositions exist.
