Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470462, here are decompositions:

19 + 31470443 = 31470462
53 + 31470409 = 31470462
83 + 31470379 = 31470462
103 + 31470359 = 31470462
109 + 31470353 = 31470462
139 + 31470323 = 31470462
239 + 31470223 = 31470462
241 + 31470221 = 31470462

Showing the first eight; more decompositions exist.
