Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558766, here are decompositions:

7 + 31558759 = 31558766
37 + 31558729 = 31558766
73 + 31558693 = 31558766
103 + 31558663 = 31558766
139 + 31558627 = 31558766
199 + 31558567 = 31558766
277 + 31558489 = 31558766
313 + 31558453 = 31558766

Showing the first eight; more decompositions exist.
