Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469258, here are decompositions:

19 + 31469239 = 31469258
61 + 31469197 = 31469258
127 + 31469131 = 31469258
157 + 31469101 = 31469258
397 + 31468861 = 31469258
409 + 31468849 = 31469258
661 + 31468597 = 31469258
787 + 31468471 = 31469258

Showing the first eight; more decompositions exist.
