Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562554, here are decompositions:

3 + 31562551 = 31562554
11 + 31562543 = 31562554
53 + 31562501 = 31562554
71 + 31562483 = 31562554
113 + 31562441 = 31562554
131 + 31562423 = 31562554
197 + 31562357 = 31562554
263 + 31562291 = 31562554

Showing the first eight; more decompositions exist.
