Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470756, here are decompositions:

47 + 31470709 = 31470756
103 + 31470653 = 31470756
127 + 31470629 = 31470756
137 + 31470619 = 31470756
193 + 31470563 = 31470756
199 + 31470557 = 31470756
313 + 31470443 = 31470756
347 + 31470409 = 31470756

Showing the first eight; more decompositions exist.
