Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469182, here are decompositions:

5 + 31469177 = 31469182
113 + 31469069 = 31469182
149 + 31469033 = 31469182
263 + 31468919 = 31469182
281 + 31468901 = 31469182
359 + 31468823 = 31469182
389 + 31468793 = 31469182
593 + 31468589 = 31469182

Showing the first eight; more decompositions exist.
