Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562362, here are decompositions:

5 + 31562357 = 31562362
71 + 31562291 = 31562362
89 + 31562273 = 31562362
101 + 31562261 = 31562362
131 + 31562231 = 31562362
149 + 31562213 = 31562362
263 + 31562099 = 31562362
269 + 31562093 = 31562362

Showing the first eight; more decompositions exist.
