Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541556, here are decompositions:

29 + 31541527 = 31541556
47 + 31541509 = 31541556
73 + 31541483 = 31541556
89 + 31541467 = 31541556
107 + 31541449 = 31541556
127 + 31541429 = 31541556
139 + 31541417 = 31541556
157 + 31541399 = 31541556

Showing the first eight; more decompositions exist.
