Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556848, here are decompositions:

101 + 31556747 = 31556848
107 + 31556741 = 31556848
311 + 31556537 = 31556848
347 + 31556501 = 31556848
359 + 31556489 = 31556848
431 + 31556417 = 31556848
467 + 31556381 = 31556848
569 + 31556279 = 31556848

Showing the first eight; more decompositions exist.
