Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469030, here are decompositions:

3 + 31469027 = 31469030
37 + 31468993 = 31469030
67 + 31468963 = 31469030
127 + 31468903 = 31469030
181 + 31468849 = 31469030
331 + 31468699 = 31469030
433 + 31468597 = 31469030
457 + 31468573 = 31469030

Showing the first eight; more decompositions exist.
