Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469058, here are decompositions:

17 + 31469041 = 31469058
31 + 31469027 = 31469058
139 + 31468919 = 31469058
157 + 31468901 = 31469058
197 + 31468861 = 31469058
281 + 31468777 = 31469058
331 + 31468727 = 31469058
359 + 31468699 = 31469058

Showing the first eight; more decompositions exist.
