Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470694, here are decompositions:

41 + 31470653 = 31470694
53 + 31470641 = 31470694
71 + 31470623 = 31470694
113 + 31470581 = 31470694
131 + 31470563 = 31470694
137 + 31470557 = 31470694
251 + 31470443 = 31470694
401 + 31470293 = 31470694

Showing the first eight; more decompositions exist.
