Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469282, here are decompositions:

3 + 31469279 = 31469282
43 + 31469239 = 31469282
73 + 31469209 = 31469282
139 + 31469143 = 31469282
151 + 31469131 = 31469282
181 + 31469101 = 31469282
241 + 31469041 = 31469282
379 + 31468903 = 31469282

Showing the first eight; more decompositions exist.
