Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469082, here are decompositions:

13 + 31469069 = 31469082
41 + 31469041 = 31469082
89 + 31468993 = 31469082
163 + 31468919 = 31469082
179 + 31468903 = 31469082
181 + 31468901 = 31469082
233 + 31468849 = 31469082
383 + 31468699 = 31469082

Showing the first eight; more decompositions exist.
