Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562334, here are decompositions:

5 + 31562329 = 31562334
43 + 31562291 = 31562334
53 + 31562281 = 31562334
61 + 31562273 = 31562334
71 + 31562263 = 31562334
73 + 31562261 = 31562334
103 + 31562231 = 31562334
197 + 31562137 = 31562334

Showing the first eight; more decompositions exist.
