Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470482, here are decompositions:

13 + 31470469 = 31470482
73 + 31470409 = 31470482
103 + 31470379 = 31470482
223 + 31470259 = 31470482
283 + 31470199 = 31470482
331 + 31470151 = 31470482
409 + 31470073 = 31470482
751 + 31469731 = 31470482

Showing the first eight; more decompositions exist.
