Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562506, here are decompositions:

5 + 31562501 = 31562506
23 + 31562483 = 31562506
83 + 31562423 = 31562506
149 + 31562357 = 31562506
233 + 31562273 = 31562506
263 + 31562243 = 31562506
293 + 31562213 = 31562506
389 + 31562117 = 31562506

Showing the first eight; more decompositions exist.
