Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470282, here are decompositions:

23 + 31470259 = 31470282
59 + 31470223 = 31470282
61 + 31470221 = 31470282
73 + 31470209 = 31470282
83 + 31470199 = 31470282
89 + 31470193 = 31470282
131 + 31470151 = 31470282
139 + 31470143 = 31470282

Showing the first eight; more decompositions exist.
