Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562466, here are decompositions:

17 + 31562449 = 31562466
37 + 31562429 = 31562466
43 + 31562423 = 31562466
109 + 31562357 = 31562466
137 + 31562329 = 31562466
167 + 31562299 = 31562466
193 + 31562273 = 31562466
223 + 31562243 = 31562466

Showing the first eight; more decompositions exist.
