Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558706, here are decompositions:

13 + 31558693 = 31558706
43 + 31558663 = 31558706
73 + 31558633 = 31558706
79 + 31558627 = 31558706
139 + 31558567 = 31558706
307 + 31558399 = 31558706
379 + 31558327 = 31558706
397 + 31558309 = 31558706

Showing the first eight; more decompositions exist.
