Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470334, here are decompositions:

11 + 31470323 = 31470334
41 + 31470293 = 31470334
113 + 31470221 = 31470334
167 + 31470167 = 31470334
191 + 31470143 = 31470334
347 + 31469987 = 31470334
431 + 31469903 = 31470334
521 + 31469813 = 31470334

Showing the first eight; more decompositions exist.
