Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469558, here are decompositions:

31 + 31469527 = 31469558
151 + 31469407 = 31469558
271 + 31469287 = 31469558
349 + 31469209 = 31469558
457 + 31469101 = 31469558
709 + 31468849 = 31469558
859 + 31468699 = 31469558
1087 + 31468471 = 31469558

Showing the first eight; more decompositions exist.
