Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469222, here are decompositions:

13 + 31469209 = 31469222
79 + 31469143 = 31469222
181 + 31469041 = 31469222
229 + 31468993 = 31469222
373 + 31468849 = 31469222
523 + 31468699 = 31469222
751 + 31468471 = 31469222
769 + 31468453 = 31469222

Showing the first eight; more decompositions exist.
