Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568944, here are decompositions:

5 + 31568939 = 31568944
23 + 31568921 = 31568944
47 + 31568897 = 31568944
101 + 31568843 = 31568944
383 + 31568561 = 31568944
401 + 31568543 = 31568944
521 + 31568423 = 31568944
557 + 31568387 = 31568944

Showing the first eight; more decompositions exist.
