Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474770, here are decompositions:

7 + 31474763 = 31474770
23 + 31474747 = 31474770
37 + 31474733 = 31474770
79 + 31474691 = 31474770
83 + 31474687 = 31474770
97 + 31474673 = 31474770
101 + 31474669 = 31474770
193 + 31474577 = 31474770

Showing the first eight; more decompositions exist.
