Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470844, here are decompositions:

11 + 31470833 = 31470844
17 + 31470827 = 31470844
191 + 31470653 = 31470844
263 + 31470581 = 31470844
281 + 31470563 = 31470844
401 + 31470443 = 31470844
491 + 31470353 = 31470844
521 + 31470323 = 31470844

Showing the first eight; more decompositions exist.
