Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470252, here are decompositions:

29 + 31470223 = 31470252
31 + 31470221 = 31470252
43 + 31470209 = 31470252
53 + 31470199 = 31470252
59 + 31470193 = 31470252
101 + 31470151 = 31470252
109 + 31470143 = 31470252
179 + 31470073 = 31470252

Showing the first eight; more decompositions exist.
