Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556524, here are decompositions:

23 + 31556501 = 31556524
47 + 31556477 = 31556524
101 + 31556423 = 31556524
107 + 31556417 = 31556524
281 + 31556243 = 31556524
383 + 31556141 = 31556524
443 + 31556081 = 31556524
491 + 31556033 = 31556524

Showing the first eight; more decompositions exist.
