Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470184, here are decompositions:

17 + 31470167 = 31470184
41 + 31470143 = 31470184
197 + 31469987 = 31470184
281 + 31469903 = 31470184
401 + 31469783 = 31470184
443 + 31469741 = 31470184
461 + 31469723 = 31470184
563 + 31469621 = 31470184

Showing the first eight; more decompositions exist.
