Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469090, here are decompositions:

97 + 31468993 = 31469090
127 + 31468963 = 31469090
229 + 31468861 = 31469090
241 + 31468849 = 31469090
313 + 31468777 = 31469090
547 + 31468543 = 31469090
619 + 31468471 = 31469090
643 + 31468447 = 31469090

Showing the first eight; more decompositions exist.
