Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562314, here are decompositions:

23 + 31562291 = 31562314
41 + 31562273 = 31562314
53 + 31562261 = 31562314
71 + 31562243 = 31562314
83 + 31562231 = 31562314
101 + 31562213 = 31562314
197 + 31562117 = 31562314
257 + 31562057 = 31562314

Showing the first eight; more decompositions exist.
