Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534556, here are decompositions:

3 + 31534553 = 31534556
13 + 31534543 = 31534556
73 + 31534483 = 31534556
127 + 31534429 = 31534556
223 + 31534333 = 31534556
373 + 31534183 = 31534556
439 + 31534117 = 31534556
499 + 31534057 = 31534556

Showing the first eight; more decompositions exist.
