Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470166, here are decompositions:

23 + 31470143 = 31470166
179 + 31469987 = 31470166
263 + 31469903 = 31470166
317 + 31469849 = 31470166
353 + 31469813 = 31470166
383 + 31469783 = 31470166
443 + 31469723 = 31470166
587 + 31469579 = 31470166

Showing the first eight; more decompositions exist.
