Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476418, here are decompositions:

5 + 31476413 = 31476418
47 + 31476371 = 31476418
101 + 31476317 = 31476418
167 + 31476251 = 31476418
179 + 31476239 = 31476418
269 + 31476149 = 31476418
359 + 31476059 = 31476418
401 + 31476017 = 31476418

Showing the first eight; more decompositions exist.
