Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556452, here are decompositions:

29 + 31556423 = 31556452
71 + 31556381 = 31556452
149 + 31556303 = 31556452
173 + 31556279 = 31556452
251 + 31556201 = 31556452
311 + 31556141 = 31556452
353 + 31556099 = 31556452
419 + 31556033 = 31556452

Showing the first eight; more decompositions exist.
