Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562376, here are decompositions:

19 + 31562357 = 31562376
29 + 31562347 = 31562376
47 + 31562329 = 31562376
103 + 31562273 = 31562376
113 + 31562263 = 31562376
163 + 31562213 = 31562376
239 + 31562137 = 31562376
257 + 31562119 = 31562376

Showing the first eight; more decompositions exist.
