Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567354, here are decompositions:

41 + 31567313 = 31567354
83 + 31567271 = 31567354
113 + 31567241 = 31567354
197 + 31567157 = 31567354
263 + 31567091 = 31567354
311 + 31567043 = 31567354
443 + 31566911 = 31567354
491 + 31566863 = 31567354

Showing the first eight; more decompositions exist.
