Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469798, here are decompositions:

37 + 31469761 = 31469798
67 + 31469731 = 31469798
109 + 31469689 = 31469798
127 + 31469671 = 31469798
211 + 31469587 = 31469798
229 + 31469569 = 31469798
271 + 31469527 = 31469798
331 + 31469467 = 31469798

Showing the first eight; more decompositions exist.
