Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562508, here are decompositions:

7 + 31562501 = 31562508
41 + 31562467 = 31562508
59 + 31562449 = 31562508
67 + 31562441 = 31562508
79 + 31562429 = 31562508
151 + 31562357 = 31562508
179 + 31562329 = 31562508
227 + 31562281 = 31562508

Showing the first eight; more decompositions exist.
