Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470396, here are decompositions:

17 + 31470379 = 31470396
37 + 31470359 = 31470396
43 + 31470353 = 31470396
59 + 31470337 = 31470396
73 + 31470323 = 31470396
103 + 31470293 = 31470396
137 + 31470259 = 31470396
173 + 31470223 = 31470396

Showing the first eight; more decompositions exist.
