Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470174, here are decompositions:

7 + 31470167 = 31470174
23 + 31470151 = 31470174
31 + 31470143 = 31470174
101 + 31470073 = 31470174
107 + 31470067 = 31470174
137 + 31470037 = 31470174
251 + 31469923 = 31470174
271 + 31469903 = 31470174

Showing the first eight; more decompositions exist.
